Gympasaurus-Rex 

A slang for someone who has a disability with their walk that makes them walk like a T-Rex. This is generally funny because you can outrun one due to their gymp status.

Shavonnie is such a Gympasaurus-Rex, I love how she can't do shit about it.

gumpasaurus rex 

the words gump and tyrannosaurus rex put together. to be gumpy means to look stupid or really goofy or lame. a tyrannosaurus rex is the gumpiest dinosaur ever. so when you call someone a gumpasaurus rex you are saying that they are far beyond being gumpy.

mike: look at josh over there, hes such a weirdo.
sam: wow he looks really goofy, call him over here.
mike: hey you, gumpasaurus rex, come over here!

Gimpasaurus Rex 

Tyrannosaurus Rex's that are heavily into BDSM. Just a kinky dinosaur.

Or to be used as an adjective for someone who is really into BDSM.

George: "Me and the Missus like to spice up the weekends with a bit whipping and paddling. She just loves being tied up while I spank her."
Kurt: "Woah, dude so you're like a Gimpasaurus Rex."
George: "Yeah, I suppose you could say that."

{George proceeded to put his hands on hips like superman with his hair blowing in the wind}

"I AM A GIMPASAURUS REX!!!!"
