When the booty on a female is too big to be true. So big and perfectly shaped, no one will ever believe you. That's when you know it's ok to use the term Donkasaurus Rex.

Any one, particularly a dude trying to brag about himself to anyone who will listen about anything he feels is note worthy..... Often obnoxious, uber basic, small penis and lies about how much sex he has, money he makes, etc.... Often unpopular with the ladies and is a one date wonder ... But, is in such denial of his douchary he blames the chicks....
That guy is a total Bragasaurus Rex! He couldn't stop bragging about himself or his lame ass life if he tried.
