couch farts 

When someone farted so much while sitting on the couch. Once they leave and someone else sits down they can still smell the fart, possibly taste.

My father was sitting on the couch and when I sat down next all I could smell was couch farts.

Depressed Couch Farts 

Farts that shoot straight into the couch cushion that remain trapped there until they force their way to the surface and out of the cushion. This usually occurs when your fat ass sits on the cushion or gets up, causing air flow to push the depressed couch farts out.

Did you fart?

No, those are old depressed couch farts. It escaped when I got up.
