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."
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"
Yikes! look at the Douchosaurus Rex in the "wife beater" over there. They just don't grow "mullets" like that anymore.
one who opposes anal sex..and gay acts without a "no homo" added at the end of the phrase. but in reality... a douchasauous rex is the king of all douchasaurous's..the prime douchasaour. hes clearly the best douche of them all. mostly douche..and mostly king.
