A fart, a really smelly fart. You know its a wagerbomb because of the warm feeling on your asshole as you let it rip. A wagerbomb can lead to a shart which requires a courtesy wipe.
Guy 1: Man my asshole hurts. Guy 2: umm why? Guy 1: I dropped a wagerbomb and i think it actually burned my asshole, like 3rd degree burn. Guy 2: That's gross
