My boyfriend acts like a doucheasaurus 95% of the time.
I dated this guy for a few months and found out later that he was engaged. He denied it and said he wasn't married, so I emailed him his wedding registry. He said "I didn't want to tell you this way" WHAT a DOUCHEASAURUS!
A person who is acting more than a douche; when the word "douche" is not enough to describe a persons dumb decisions, actions, believes, or thoughts. This term could also be used to a person who is larger than others.
"Hey look, I can dead lift 515 pounds!" Mike exclaimed. "Wow, he is such a doucheosaurus." Peter stated aloud.
The extended version of douche for those guys and girls who can't just be a douche. They're over ridiculous, a veteran idiot, make it not even your game anymore, are extremely lazy, think they're huge, love public humiliation and pick on smaller people for their sole entertainment.
"Jackie totally was making fun of Cindy's little brother, he thinks he's such a pro. That ass..."
"Yeah I noticed after he tried to pants me, big head and little arms that douchasaurus rex."
