An expression reminiscent of the Golden Age of the Jurassic Era, when ferocious lizards roamed the land. Thus use of the expression refers to anything that is big and bad, or totally bad-ass. Use of the word furthers the quest to win Alex $5 out of Zach's pocket for spreading a word.

vb.

To be set upon by invasive action while sitting on the toilet; whether by someone banging on the door, peering through the gap in the door to the sitter's stall, etc. Reference to Jurassic Park scene where Gennaro (film, or Ed Regis in the book), is terrorized, then eaten by a T-Rex.
1. I hate taking a dump anywhere close to 2pm. I always get T-Rexed by that idiot who restocks the shit tickets.

2. The stall doors are always closed at the airport, so they always look full-up. I T-Rexed 3 guys before I found an empty seat.

3. Will you stop banging on the damn door? Dad already T-Rexed me a minute ago! I'll be done in a minute or two!
