I'd like to smash an underage girl
Why do you want to smash an underage girl?
I'm jolly and I like trolling people.
Trolling while being fun for you is not good and it can hurt other people and if you troll and do something to an underage girl you could be breaking the law. It could have you be sent to jail.
I did it before and got away with it.
It doesn't mean that you will always get away with it. It is bad to break the law and do things like that. Your luck will run out eventually and you will be in a lot of trouble.
