Teachers pet

A person who always snitches on you when you take a step forward at them or they challenge to fight you on a damn Monday or Wednesday. When you actually fight them, or actually touch them lightly, they will either:
Snitch
Cry to the teacher
and my favorite one..
Try to attack you but you KTFO of them.

This Teachers pet is so annoying! When will he ever stop picking and snitching on me??
