Guy2: Aww man that fart is so bad that I feel warm, and it smells like a hot pile of shit, you suck
Guy1: Yeah, that's a specially made carpet fart for ya
the act of sitting on a carpet and farting, allowing the fart to be picked up by the carpet, therefore, eliminating all sound.
I was with my boyfriend last night, and it started to smell really bad, but i didnt hear a fart sound. I assume he must have carpet farted.
