t-rexin

When someone gets so drunk they are beyond blacked out, and are so drunk that it is a state of mind, causing said person to hold their arms in a perched position like a T-Rex.

There has been some serious t-rexin the past few nights of partying.

T-Rexin

Bobbing up and down on the dance floor with your arms scrunched up to your sides mimicking a Tyrannosaurus Rex. The most fool proof dance move to grab the opposite sexes attention apart from the robot. If you add a growl to this dance move it will ensure you a phone number 60% of the time every time.

Friend: Wow, he's fine. How did you get that guy to ask you out?
Me: Totally started T-Rexin to Dubstep at the club last weekend
Friend: GTFO, I'm switchin up my robot moves
