Mr. Hanky, Terrance and Phillip, fart jokes, Benny Hill or just about any humor that get a reaction from an audience by exaggerating normal bodily functions. Some examples could include diarrhea(cha cha cha), farts, piss, burps, snot, or menstruation. Usually thought to be low brow or unsophisticated humor by the upper class. But, amusing to most human beings nonetheless. If you can picture the Queen on the crapper - you know what I mean!
