Cheat Chain Dilemna
When one student copies answers from the "smart" student on a particular test/homework/exam. And, to the smart student's dismay, the cheater got a better score, leaving the "smart" kid dumbfounded, confused, and in a world of self-loathing.
"The Cheat Chain is wonderful in theory, but if the cheater gets a better score than the cheatee, the Cheat Chain Dilemna is in effect."
