Fart Blister 

When conditions are perfect (e.g. You are sitting on a flat to semi-concave, non-porous surface) and you release a fart that cannot immediately escape the confines of your ass cheeks. The fart will remain in place until you shift your weight or raise at least one ass cheek to "pop" the blister.

I feel weird telling you this, but I find fart blisters sexually arousing

A large muffler that creates a farting noise when added to the exhaust system of a four cylinder car. Generally having a large, chrome tip of about 4" in diameter or larger. These mufflers remove backpressure from the exhaust while also reducing low end torque in most engines, this occasionally makes cars slower than stock off the line and not much faster anywhere else.

"Why does every moron with a civic and $300 feel the need to install a fart blaster?"

One who uses great force to let out extreme waves of gaseous, toxic odours and does so intentionally. One who not only profusely and deliberately expels all nasty smelling gases from body but does so with pride.

The kids and I were choking on this horrible odour in the room, that fartblaster had no shame.
