"Wow, did you hear what Jim had to say at the party last night?"
"Yeah, he came from nowhere on his douchecanoe and made everyone feel uncomfortable."
An informal gathering of 2 or more douchebags in a public forum such as in front a movie theater, at the bar of a TGI Fridays, or in the parking lot of the less favored Mall in town.
