Wax On, Wax Off

Situation:

A young woman becomes angry when she discovers that her boyfriend is using a dating app while he is still with her. He leaves, and she calls him later to pick up some of his belongings—in front of her apartment. Instead, she leaves the items upstairs, and when he arrives, she runs at him, hitting him with both hands.

Trial:

He testifies, she testifies. He describes his defense against his girlfriend as, "Like ‘wax on, wax off’, from The Karate Kid ." Both of them had marks and bruises. However, photographs showed that the marks and bruises on the boyfriend were located where you’d expect for someone defending himself, whereas the girlfriend had bruising on her knuckles, which even she said she hit him with.
