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.
Kurt was completely ignoring all of his guests, so Chad proceeded to giving his carpet a thorough Stanley Steamer, though this wouldn't be the first time...

A Stanley steamer can be done one of two ways, 1) turn the AC up so it's cold in your place. Then take a shit on your victims chest. Your poo will be warm enough in the cold room to begin steaming. 2) take someone outside in the cold or camping. Con them into sleeping shirtless. Drop a hot one on their chest. Stanley would be proud.
