When a person ditches a class, while there is a major test.

There are 5 tests tomorrow at school, I am going to be pullin' a Jack.

being a Jack 

This is when someone (usually named jack) is hiding their sexuality for example they are gay but will hide it and make fun of other heterosexual males calling them gay on the off chance he can convert one of them so therefore when he comes out the closet he isn't alone.

Hey you, why you being a Jack? No one likes a Jack.
