There's no justification. Either you don't realize how truly damaging it can be physically and mentally, how common it is for someone to have at least be assaulted once, or you just dont care. Or perhaps it's happened to you and you're trying to make light of it, in which case I'd recommend therapy.
If you still think it's funny, yd too, I'd invite you both to give it a try. Share your comedic tale with us afterward.
