Defunker 

another clothing site that now dominates the ads on urban dictionary. Very similar to busted tees and sinful shirts. Defunker sells a bunch of shirts that aren't funny without an explanation or commentary. All of their models are probably supposed to look like "everyday" people, but are just plain stupid.

The model the new ads for Defunker on Urban Dictionary's face makes me sick.
