A fat douche bag with a full beard or chin strap.
The beard is dirty. It will usually contain some food particles or maybe even insects.
Picture a douche bag with a dirty Abe Lincoln style facial hair.
Tom: Its nasty dude, I saw him eat a bean from it
Commonly sported by (but not limited to) beta-males in urban areas, the douche beard has spread into the realm of effete Jr. College wannabes and self-hating white hip-hop poseurs.
Douche beards are the mullets of this millennium and should be relegated to men of Asian and Latin descent who lack sufficient facial hair follicles to grow a full beard. Anyone else electively grooming their facial hair in this manner is immediately subject of ridicule and derision and of questionable taste/intellect.
That Guy: Wow.
Examples include Ali G, that douchey guy from The Backstreet Boys, and guys who purse their lips for photos. See also "Jersey Shore."
Often accompanied by excessive Drakkar Noir cologne, Overuse of Axe body spray, blingy diamond earrings, and those shaved-in hair stripes, like MC Hammer or Bobby Brown.
