(pronunciation: brō pä) n. A fuckin' totally douchebag move. Like, maybe you hit on your bro's girl, or smoke all his greens. (cp. Party foul; ORIGIN late 17th cent., French "faux pas" literally "false step"; and abbreviation "Bro." of English "brother" from Old English brōþor, from Proto-Germanic brōþēr, from Proto-Indo-European *bʰréh₂tēr.)
Aw! Dude! Bro pas! You totally spilled Nat all on my fuckin' Entourage DVDs!
