douchebaginitis

The condition in which one has become a douchebag. This condition can be passed on from individual to individual through popped collars, sweatbands, cop sunglasses, and the every contagious tool syndrome. The only cure for douchebaginitis is a thorough ass stomping courtesy of Oscar the Grouch or having cinder blocks thrown at one's face.

Stay away from that popped collar, you might catch douchebaginitis
