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."
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!
Someone who is a massive douche bag and keeps wondering why people want to leave thier work section when they keep being a huge douche bag and asshole.
MSgt is a Doucheasaurusrex, he got pissed at me for asking Luis for help then wondered why we all want toget out early.
By far the largest douche in its environment. Douchosaurus Rex is a fierce predator that walks around on two powerful legs. This meat-eater has a huge head and very small brain. Well regarded as the King of the douche bags and feared by all lesser douches.
That Douchosaurus Rex looks like he is ready to "throw down"...get ready to "bolt"
