Koger 

A guy who uses girls for sexual, financial, or influence gains. Often cheats and manipulates.

Turns out he was a Koger after all; he was getting money from all three of us to “get by on rent”.

Mr.koger 

Mr.Koger is a cocky, bald-headed geometry teacher. He teaches CP but treats it like honors. His roasts are lame and his life is terribly sad. Everyday he spends hours driving to his lousy job, where he gets treated like crap by low-life students. Following this he spends more hours going back to his house.

Koker 

A chem teacher who wears Hawaiian shirts on Thursdays, likes puns, and occasionally tells long stories that either end with a pun or relate to a chem topic (or both).
Note a koker will use peanut butter sandwiches as a simile for almost all types of bonding.
