Is someone you clearly aren't dating in real life and you clearly aren't dating to help you in math class (for you are definitely the intelligent one of the two). A math boyfriend is someone you are using just to give you the much needed attention you are lacking and to give you the idea of actually being in a relationship, in which there is seriously no commitment. Basically making you a needy douche.
You: "Oh hey math boyfriend!" (Hugs) "I really missed you!"
Math Boyfriend: "Hey...so how do you do number seventeen on the last set?"
