A male douchebag that brags about things not even worthy of bragging about.
"Yo, I just benched 200 lbs for a half a rep! Top that!" - what a douchebrag!
A grade A douchebag who brags about his latest endeavor. Someone who likes getting attention and makes an ass of himself while getting it.
Ameet: "I hate it when my celebrity friends call using a *blocked* number. The downside of winning an Oscar or two."
Diane: "Ameet's such a douchebrag".
