Snaggle nail

A single nail that has managed to go untrimmed for an abnormally long period of time. It has started to chip and has become a weapon comparable to that of a steak knife. Is often accompanied by copious amounts of bacteria.

Last night while Ryan was trying to penetrate me with his meat stick, he accidentally jabbed my ankle with his snaggle nail causing severe lacerations and abruptly destroying any possibility of sex.
