fifi bag
n.— «Actually, the instructions for such an organic liason originate witth the invention of the famous “fifi bag,” used since the first horny prisoner in some long ago jail cell discovered that a rubber glove, or baggie, or sheep’s bladder, or anything else that would hold intact some substance such as raw liver, or hand lotion, or even some nice, warm oatmeal. would be, with just a dash of imagination, a better-than-nothing replacement for the warm, slick inner walls of one’s favorite orifice. this discovery led to the realization that a great many of our little green and yellow buddies(as zappa called them) could be used in much the same way.» —“Re: What the hell happened?” Usenet: alt.anger June 9, 1998.
