Ahaha, they don't tickle you after you flail your fist into their face in a snap reflex to being tickled. Works every time, I assure you!

I'm very ticklish, but people don't tickle me as when they do, they get hurt. I also hyperventilate if they somehow manage to hold me down, but I think that's only happened twice because not many people have the ability to hold someone down and tickle them at the same time.

I don't laugh as much as I do struggle to breathe, though, so I imagine it's not extremely fun in the first place for the tickling party.
