Person in the class that always does errands for the teacher or class to get on their good side, but usually faking it because they'd never do it for no reward
Teacher: Sally can you bring me the tissues 1 foot in front of me?
Sally: hell no
*Jessie runs up and hands tissues*
Jessie: here you go!
Teacher: remind me to give you extra credit for that Jessie
Jessie: sure thing, i'll scrub your toes later
Sally: wtf.. what a class bitch
