T Rex 

When your lady is in the "reverse cowgirl" position, you put clench your hand with the middle knuckle raised (similar to the frogging punch). With this protruding knuckle you then place it on her spine and rub back in forth. The feeling is very intense/ticklish. It will cause her to moan in a weird fashion and her arms will become incapacitated past the forearms for a brief moment.

Some women also seem to do weird things with their mouths during the moment.

man 1: "my girlfriend is super mad at me"
man 2: "why is that"
man 1: "I was T Rexin' her for a while and now she has chronic back spasms"

T Rex 

A girl that when drunk is half human half dinosaur. She walks, eats, throws up and even growls like a T Rex. Nothing stands in her way when she has the late night munchies. A girl in her mid 20's that takes down a whole crock pot of velvetta cheese dip and a large pizza in one afternoon. A girl who tries to talk while she eats but sounds like a T Rex on a man hunt.

Tell him to walk on down here and say hello to the T Rex
