any overly dramatic way of breaking wind; e.g.: "pull my finger", raising one leg, or making a grunty face.
Everyone knew what was about to happen by his gastheatrics, and the only hope was that he would accidentally crap his pants when he farted.

The acting of farting in an overly dramatic way, such as lifting one leg, making a grunt face, or having someone pull your finger.
