To commence farting as you start walking down a hallway or passage - trying to make the fart last all the way to the end. Ensures a consistent unpleasant experience for any followers
Man! - I just followed the longest farttrain ever - its was awful!
When someone drops a fart of such magnitude that you react as if you were physically punched in the face. Its like being assaulted by death.
I was in the elevator at work and i swear to god Jack delivered a Fart Punch to every one of us in there. I didnt here it coming but when it hit i cried like a little girl that just learned life has consequences.
