Four gay men walk into a bar. After a few beers, they decide to have a farting contest.
The first guy prepares himself, and let's out a short "Pffffff". The other three nod, saying it wasn't bad.
The second guy goes ahead, with a longer "Pffffffffffft". They nod, acknowledging the length and slight wet ending.
Third guy goes ahead: "Pffffffffffffffffffsht". They all clap, saying that's a brilliant one.
Finally, the fourth guy goes ahead, and lets out a massive ripper. The other three look at him: "Oh, so you're a virgin ?"
Translated from French, so sorry if it's a bit ****.
