JJ is what you would call a seventh-grade math teacher who has no purpose in life and is very submissive. Basically a term for any adult who is useless without help from others, but it is most used for
math teachers, especially ones in
elementary school. JJs usually are friends with jenoms (slang for big mean ladies) because jenoms will always boss the JJs around and tell them
what to do, giving their life purpose.
Teacher: Today we are going to learn math...
Principal: No you will not. We are going to have gym class
on the roof today!
Teacher: Yes. We will do what
the principal says because I am such a bottom.
Student: Damn, what a JJ.
Jenom: I am going to control your every action.
JJ: That's perfect!
Some kid named Mikal: Bro why is that dude such a JJ...
JJ: You will never get the mind ball Ryneil!
Ryneil: Ugh yes I will!
JJ: Okay fine you can take it.
Doof: This guy is such a JJ.
