A joke having to do with disgusting acts of sexual innuendo or other things people might find grotesque.

when you're hungover as shit after a spending a night drunk as a skunk

A joke that can be seen two ways, innocent or dirty.

The funniest things in the world to listen to when your dad is drunk.

Any joke containing at least 75% sexual innuendo, coarse language, graphic and possibly pornographic imagery, and at least one slur or derogatory remark concerning ethic, national, racial background, religion, sexual orientation, and physical or mental handicap. Joke must not be able to be repeated in front of one’s mother; however, joke’s level of offense and thus its quality is exponentially increased with tactless references to one’s fat, stinking, dumb, greasy, illiterate, and over-sexed mama. Jokes deemed off color, in poor taste, and otherwise written on men’s restroom’s walls (whether in pen or body excrement) are acceptable.
