Shinai

A practice weapon for sword-based martial arts. Thought to be relatively harmless, but when used with even a moderate amount of accuracy and force may be used to break bones.

I can't find anyone to spar with me, the last time i used my shinai I broke someone's wrist.

shitnail

N. This describes when one does not wipe (in going to the bathroom) properly, and thus infestations of what was to be wiped are now pushed under the poor sap’s fingernail(s). (This term was begun by Artie Lange of the Howard Stern Show.)

“Yo Bill what’s that under your fingernail? You stupid ass, can’t you wipe yourself? Now you’ve got shitnail.”

shitnami

The massive wave of toilet water that is displaced when a giant turd is blasted out of your ass.

The explosive dump I just took caused a massive shitnami. Now there is debris all over the floor.
