Alright listen up, genius. This joke is funny because "cheetahed" sounds like "cheated." Cheating is when someone in a relationship messes around with someone else. The joke uses the word "cheetah", which is a type of fast African cat. The pun makes it funny. You probably don't get any action anyways.
