It took 20 years for women to work their way into the UFC. It took 4 minutes and 49 seconds for them to prove to doubters why they belonged.

Ronda Rousey, the former Olympian who rose from obscurity to stardom in the blink of an eye, defended her UFC bantamweight strap on Saturday night, adding the right arm of Liz Carmouche to her growing collection in the main event of UFC 157. The result was admittedly predictable, but the execution was undeniably electric.

Carmouche seized Rousey's back midway through the first round, nearly securing a choke then a neck crank that would have stunned the world, before tumbling off and succumbing to Rousey's trademark armbar. The moment not only served as vindication for Carmouche, who many said didn't stand a chance, but also Rousey and women's mixed martial arts as a whole. The 26-year-old displayed the heart of a UFC champion, and ultimately, WMMA couldn't have asked for a louder, more emphatic, introduction to the masses.

Ronda, armbar Rnd. 1. We should all probably get used to hearing that. #UFC157 #ufc #mma

@vitorbelfort @rondarousey your arm bar is great u got to teach me so when I fight #jonjones next time I will take that arm home

— Vitor Belfort (@vitorbelfort) February 24, 2013

Pretty amazing moment in time tonight Rousey vs Carmouche #UFC157

— Sean Shelby (@seanshelby) February 24, 2013

whoever said that Hendo vs Machida was "the real main event", I wonder if they're glad that it wasn't. Ronda n Liz WERE the real main event.

— Vinny Magalhaes (@VinnyMMA) February 24, 2013

Man doesn't girls know how to defend an arm bar yet, one fight at time they will get better.

— Roy Nelson (@roynelsonmma) February 24, 2013

MACHIDA OUTPOINTS HENDERSON

Dude didn't come to fight @danhendo !

— Daniel Cormier (@dc_mma) February 24, 2013

There are very few things on Earth I dislike more than Machida's fighting style...

— Michael Chandler (@MikeChandlerMMA) February 24, 2013

I disagree with the @danhendo score! I thought Dan won that fight.

— Cung Le (@CungLe185) February 24, 2013

@danhendo score a ton of inside leg kicks

— Cung Le (@CungLe185) February 24, 2013

I'd like to see Machida on Dancing with the Stars

— Cub Swanson (@CubSwanson) February 24, 2013

I know that's not what fans (or myself) wanted to see but that was extremely technical stand up. Surprised Dan didn't try more takedowns.

— Kyle Kingsbury (@Kingsbu) February 24, 2013

So does Loyoto get a title shot now or do you guys wanna wait to see what happens between the Gustafsson and Mousasi fight? @ufc

— Ulysses Gomez (@uselessgomez) February 24, 2013

LMAO at Chuck Liddell asking @joerogan if Hendo and Machida landed anything at all? #ufc157

— Siyar The Great (@SiyarTheGreat) February 24, 2013

That fight SUCKED! #UFC157

— Tim Kennedy (@TimKennedyMMA) February 24, 2013

Good job by @lyotomachidafw, but @danhendo is still the man in my book. #mma #UFC

— Mark Bocek (@MarkBocek) February 24, 2013

Why are they booing?

— Akira Corassani (@AkiraCorassani) February 24, 2013

What a beautiful display of Karate! Parabens @lyotomachidafw #Bushido #MartialArts

— Akira Corassani (@AkiraCorassani) February 24, 2013

Boring...looked like a pissed off drunk dad fighting his kid's Karate teacher.

— War Machine (@WarMachine170) February 24, 2013

Love hendo one of my all time fav's ...respectmachida... but that fight sucked... #ufc #Bellator #MMA

— Brian Rogers (@BRogthePredator) February 24, 2013

Machida footwork & efficiency won him the fight but not an exciting one. Gotta respect Hendo's right hand tho. Smart fight. #UFC157

— Kenny Florian (@kennyflorian) February 24, 2013

Well here's the prob. If someone fights defensively & still out scores u, then u lose. As annoying as it is, it will win fights. #mayweather

— Kenny Florian (@kennyflorian) February 24, 2013

Waiting for Dana to press a button and the octagon shrinks to the size of the bud light sign for Hendo vs. Machida

— John Cholish (@JohnCholish) February 24, 2013

Not sure how that gets scored for Henderson. #ufc157

— Jason High (@KCBanditMMA) February 24, 2013

Judges r retarded, Hendo all the way!

— Luke Rockhold (@LukeRockhold) February 24, 2013

Machida out there doing an aerobics routine #UFC157

— Derek Brunson (@DerekBrunsonMMA) February 24, 2013

I dnt even know how to score that fight. And honestly dnt want to. It sucked

— George Roop (@GeorgeRoop) February 24, 2013

Everyone is booing but i thought it was fair. What do you guys think?

— Nam Phan (@NamPhanMMA) February 24, 2013

Apologize to my fans for a boring fight, wont happen again. I appreciate the support...be back soon!

— Dan Henderson (@danhendo) February 24, 2013

— Joseph Benavidez (@JoeJitsu) February 24, 2013

Menjivar = not an easy guy to submit. Faber slipped in a beautiful #RNC #UFC157

— Kenny Florian (@kennyflorian) February 24, 2013

Awesome submission urijah. You did it :)

— Nam Phan (@NamPhanMMA) February 24, 2013

That's to bad I was hoping Ivan would've pulled it off. Great job to faber!

— Pablo Garza UFC (@PabloGarzaMMA) February 24, 2013

So is it safe to say that @urijahfaber is going to win SOTN unless Rhonda wins by armbar?

— Ulysses Gomez (@uselessgomez) February 24, 2013

Awesome work by Faber.. Yeah i personally know his strong back control &next time around wouldn't let it quite be the same. :))

— Raphael Assuncao (@RaphaAssuncao) February 24, 2013

Hi thanks for the support! I am ok no injuries sorry or the fast fight that's is the game :-)

LAWLER FLATTENS KOSCHECK

THAT'S MY BOY!!! twitter.com/matthughes9x/s…

— Matt Hughes (@matthughes9x) February 24, 2013

Way to go @ruthless_rl you looked vicious. #UFC157 powerful strikes.

— Tim Kennedy (@TimKennedyMMA) February 24, 2013

Damn Lawler beast, I thought a little premature stoppage but whoa... #UFC157

— Mark Bocek (@MarkBocek) February 24, 2013

A lot of people are giving Herb Dean a tough time for stopping the Robbie/Kos fight but remember he was the ref fot the Bermudez/Grice fight

— Ulysses Gomez (@uselessgomez) February 24, 2013

No matter if that was early stoppage there was only going to be one outcome after them bombs!!

— Ross Pearson (@RossTheRealDeal) February 24, 2013

Robbie Lawler looked like he was on a mission tonight! Looked like old-school Lawler. #ruthless #UFC157

— Kenny Florian (@kennyflorian) February 24, 2013

I agree with @joerogan it looked a little premature. But congrats to Robbie.

— Kyle Kingsbury (@Kingsbu) February 24, 2013

Nothin premature about that stoppage at all. #ufc157

— Jason High (@KCBanditMMA) February 24, 2013

Wowzer Strikeforce strikes again #UFC157

— Derek Brunson (@DerekBrunsonMMA) February 24, 2013

Kos just gave up... Robbie took his will! #ufc157

— Siyar The Great (@SiyarTheGreat) February 24, 2013

Robbie Lawler was always one my favourite fighters. @ufc Welterweights look out Ruthless is back. Shit...Wait a min I'm a #ufc welterweight
