When you walk into a room (most often the kitchen) and it's disturbingly obvious that someone just opened the trash lid, if only for a second, and let out a gas cloud of nastiness.
Usually this occurs when everybody in your shared apartment thinks it's someone else's job this month to change the kitchen trash bag.
Dude I just walked through the nastiest trash-fart in the kitchen! Who threw something away??
Man I think those girls left your party because I threw away my takeout boxes and the wretched trash-fart almost killed their friend.
If someone doesn't change the trashbag in this bitch soon, we're all gonna die from the trash farts! Whose month is it?
