A Stanley Steamer is the act in which anal sex turns into a scat-like disaster. When you pull your cock out of the ass and you get a diarrhea surprise on your chest and/or pubic region.

Stanley Steamers may be performed when you are at a friend's house to visit (eg. for a LAN party, etc.) but he's being a *very* shitty host, so you proceed to pull your pants and underwear down and rub your bare, nasty ass on one, very concentrated spot of his bedroom carpet. If he's being a particularly flagrant ass hole, proceeding to the rubbings of his bed sheets, pillow cases, and/or other miscellaneous personal belongings may ensue.

Since their motto is "Tough on dirt, gentle on carpet", the sex act entitled "the stanley steamer" is when you punch a girl in the asshole repeatedly (tough on dirt) while rubbing her pubic bush tenderly (gentle on carpet). Some consider this a contradictory act, but nothing shows your love for a woman (or man?) like a good 'ole stanley steamer.
