When you are sitting really hard on a chair and your fart has nowhere else to go but up the front!
Girl, I was working so hard at the compter I really had my butt pushed into the chair tight! I ate a lot of hormel chili and my farts had nowhere to go up the front. A real vibrating gipetto!
Something nasty and foul. Disgusting and rancid. Minging, rank, putrid.
The slang term is based upon Pinocchio’s nasty ass dad, Geppetto. Who stinks like shit all the time because of his exceptionally poor hygiene.
