Definition 1: While taking a dump you sense gas at the backdoor, you go to squeeze it out, but to your surprise the gas surrounds an extraordinarily large turd which exits forcefully, stretching your sphincter for a split second to a painful extremely wide state.
Usage Example: I just went to fart, but I turned into an ass cannon, now I can barely walk without pain.
