nose-eurysm
The bloody nose the occurs when you are squatting over the toilet to pee in a public restroom and your overly loud FUN co-worker spots a doody in a nearby bowl and shouts out loud - "DOODY WITH CORN" - but you can't laugh because a snooty co-worker is in the next stall.
The huge piece of corny shit in the ladies room was hilarious. Because a snobby co-worker was in a nearby stall and I was hovering so not to touch the gross bowl with my ass, I held back a bursting laugh which to my surprise caused a nose-eurysm.
