Top Definition
1) Someone who is so beyond intoxicated that they begin to stomp around with arms curled in and waving about uncontrollably, leaving only devastation and destruction in their path (most often on the way to the bathroom to throw up). This elusive creature may also be known by its unmistakable call of garbled words and constant repetition of the same phrase over and over again.

2) A term to describe anyone you know who is always that one person who gets way too drunk, even though they know their limits, or everyone tells them to stop drinking, yet they continue to anyway.
Noun:

1) "Dude, Jimmy turned into such a Plastorasaurus at the party last night."
2) "Don't drink too much tonight man, we don't want to see the Plastorasaurus again."

"One Tequila, Two Tequila, Three Tequila, Plastor...asaurus.....Fuck"

Adj:
"I hate it when you get so Plastorasaurus that you can't even walk across the room."
"Jesse is Plastorasaurus again, keep him away from the glass table..."
