The term given to the act describing fellatio while wearing a condom. (noun) It is derived from the theoretical accumulation of steam inside the condom while a blowjob is being administered by a warm mouth.
I thought we were going to have sex, so I put on a raincoat and then she started giving me a steamdog instead.
