Acronym for Designated Cock Blocker. This is the most unattractive female in a group of women at a nightclub or like social gathering. Her primary purpose is to remain unintoxicated and defer all advances from would be suiters.
Also, the male counterpart is the friend who won't go home or go away when you are trying to get your freak on, as it were.
O.k., first and foremost, we have to distract the D.C.B., so we can make our move.

Guy 1: Dude, man, I had a fling with this girl I really like, but man i can't get over her gorilla DCB's.

Guy 2: Yah man, I can't stand them. They should rename that song "Do your ears hang low" to "Do your boobs hang low, do they wobble to the flo"

DCB is an acronym which stands for double cock block. This is a situation when two males (of any species) are trying to have pleasurable moments together and then are disrupted by the addition of other individuals. Hence delaying their intimate rendezvous, much like ice water to the crotchal region.

Jared: You totally just DCB'ed us!
