 Get the Rexinemug.
Get the Rexinemug. A variant of roller skating and dancing combined into sweeping smooth moves at the roller palace.  Requires the use of ol-skool 4 wheel skates and Daisy Man Duke cut off's.  It combines the smooth dance moves of Saturday Night Fever with the rolling motion of skates, only broken for toe stops and strutting.
"Man look at the dude with the Levi cut off shorts and the mullet.  He's rexin all around those kids like it's '86!

Get the t-rexinmug. 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.
