Ruby

Ruby is a massive egotistical twat who loves to one up you no matter what it is, she trains judo and bjj, she will crank on any submission without giving you time to tap. She constantly brags about her music taste and is highly abusive. She is extremely condescending, all the definitions previously wrote on here are all bollocks, this is the only real one you'll find.

Woah, look at Ruby, what a twat

Hey, I'm such a Ruby, I just snapped someone's arm off in a light spar
