O.P.D. 

an organization comprised mostly of fat guys in backwards hats who think they are hard because they smell like a donkey's sweaty nutsack, enjoy kissing dudes, and dance to Will Smith like it's their job (I know kissing dudes and dancing to Will Smith are synonymous)

Although a highly secretive clan, O.P.D., scholars suggest, stands for one of the following: Overweight Pussy Douchebags; Oversized Penis Devourers; or Knuckle-Dragging, Anal-Probing, Cocksucking, Shiteating sacks of Rhinoceros spunk.

That guy has been receiving through a glory hole for the past twelve hours straight. He must be O.P.D.
