The bed/couch/etc. where you have been sleeping, lounging, eating, playing video games, watching t.v. etc. for more than a couple of days in a row, without showering or going out. You only get up to use the restroom, get something to eat/drink and then flop back down. This type of situation usually means that there is a definate funk surrounding you that smells something like a fart.

Further definition suggests that during said act, fecal matter may actually enter the urethra of said sexual protagonist thus causing great physical harm and potentially catastrophic internal sexual damage to both parties involved.
