When you feel gaseous onboard a boat from eating too many shrimp cocktails, then blast a nasty one that knocks you overboard and gives you a heart attack.Your flailing about then attracts a shark which leads to you shitting your trousers. A fourfold terror to behold.
"Well this is not a boat accident! It wasn't any propeller! It wasn't any coral reef! And it wasn't Jack the Ripper! It was a shart attack!" - Matt the Hooper
