When a female (usually) breaks up with her boyfriend, while already having another guy picked out. Her excuse for breaking up always blames the guy for the termination of the relationship. She does this to technically avoid cheating. We guys see through this ruse AKA 'double negation'.
Sarah: "I don't feel you love me anymore.
Guy: "Why would you say that? Of course I love you."
Sarah: "We should see other people."
Guy: "Are you cheating on me?"
Sarah: "No. I'm not not cheating."

And so she sees someone else...ten minutes later.
