I'm fairly sure there is no other meaning than the one to which you refer, so its perhaps more likely that you are missing the risqué point being made by assuming the prude levels are higher than you might think. A lot of the folks who make these kinds of hacks, are perfectly fine with the obscure, obscene, perverse nature of their naming of things ... Those of the anthropological inclination may decide that, in fact, an obscene name for something like this is a requisite.
