fart chair

When an office chair has been subject to that many farts, whoever sits on it is hit by a brief waft of stale fart gas.

As Leroy sat on the fart chair, he soon experienced the full bodied stench of 6 months of Bob's farts stored in the cushion.

Internet Fart Chair

Basically, a chair ususually used by
a geek, nerd, or gamer designed for
sitting long durations in front of a computer.

The "fart" comes in because typically
the padding in the chair retains the
residual flatulence which is outputted
into the chair over a long period of time by the owner.

Often times an IFC will also have holes
or other defects in it, sometimes an
arm missing, torn/holes in fabric, etc, but despite all the damage and/or smell,
the user will typically keep an IFC around until the chair starts to
deteriorate to the point of being
unuseable.

Cloth-padded chairs tend to fit the IFC
profile more perfectly since leather tends to make the fart smell "bounce off" the chair instead of getting trapped inside the padding. A true
internet fart chair may even retain the
fart smell for years.

"James finally retired his beloved
Internet Fart Chair after months of
evercrack caused the arms of the
chair to loosen and break off. "

Chair Fart 

When the chair you are sitting on makes a noise resembling the sound of a fart, especially in leather car seats or swiveling chairs. This is very annoying 100% of the time.

"Pfffffftttttt"
Girl: "Eww what was that!?"
Guy: "Relax, just a chair fart."

When one sits down in an awkward position so that he/she compresses the air between him/her and the chair, resulting in a flatulent sound.

John: Dude did you just fart?

Mike: What?! No, that was just a chair fart!

John: Then what's that smell?
