break up with friends?

[pickler]

i have a couple friends who i have come to figure that are taking advantage of me in college. they do this by copying tests/exams or my homework in exchange for almost nothing of worth to me. I have been friends with these people for couple years but they are of no value to me any more and i hate them now. I was wondering what is the best most stealthy way to just break it off and make sure they don't talk to me anymore?

Just stop replying to their texts and don't go out with them anymore.

Have sex with their girlfriends. You lose them and you gain pussy, double win!
