Stabby is a term used to describe individuals who have a strong desire to skulk around in the darkness of night and stab objects with sharp instruments. Often these objects are round and black as they remind the Stabby of their particularly bad experiences when they were small children. Often a Stabby will try and fool you into thinking they are quite intelligent, but close examination will reveal that they are nothing more that a bully looking for a school aged child to tease.
