Fart Sack 

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.
