When someone has such douchey attire that they look like they spent 2.5 hours in the mirror trying to get their image juuuuust right. Oh yeah, and they're not in high school anymore...
Ruining movies by recycling and superimposing the same retarded characters over and over again. Acting like a disconnected lunatic/fruity/Burton-sucking/songster/gay-pirate without being under the influence of copious amounts of recreational and prescription drugs in Las Vegas with Benicio Del Toro. Thus destroying a previously enjoyable movie.
Johnny Depping, Depper, Depping, Depped, Depped-Out, Depped-Up, Deppish, Deppraved, or the obscure Northern Midwest context: Johnny Deepp.

This can be applied to pets and small children by Deppish Parents, thus becoming Deppendants, The Depp-Posed.
