An armpit fart is a simulation of the sound of flatulence made by creating a pocket of air between the armpit of a partially raised arm and the hand, then swiftly closing the pocket by bringing the arm close to the torso, causing the air to push against the skin, creating the noise. Often used for humour,[1] armpit farts can be considered juvenile or crude.[2] Comedian George Carlin in LP record albums of his performances spoke of "the artificial fart under the arm."
The sound produced by armpit farting can accompany singing or other rhythm.[3]
An armpit fart can be achieved by raising an arm up, cupping the hand of the other arm over the armpit so the thumb is parallel with the Anterior Axillary Line, with the remaining fingers wrapped across the Posterior Axillary Line so that bending the arm back down pushes the remaining air out against the skin through a slight opening in the hand. The exact effort needed to create the noise can depend on the physique of both the hand and the armpit, the positioning of the hand, as well as the speed at which the arm is bent.
