For girls: If you are giving a guy a hand job, and he complains, then you take both hands and TWIST them both in the opposite directions, like a snakebite.
The sick move where you use a powerful metal clamp to hold your penis in place and you twist your body like a beyblade on top of it until your dick is all messed up.
