The weird clapping/popping sound your farts make after veeting your crotch and butt hole area. To best describe it, it sounds like passing air between 2 under inflated balloons squished together. It happens because deep inside your butt cheeks where farts first escape is so smooth that it alters the normal sound of a fart.
Friend: Why do your farts sound so weird dude?
Me: Oh, well I just veeted last night and I've been having veet farts ever since. They feel and sound so weird!!!
