I like the AKA part in my name.
I don't like the tapping idea, the general public will find that weird. OH!
what if we each had an individual sign?
like I could hold my hand in a circle shape against the side of my lips and make a small biting motion, like "mmmm bamboo."
and the bouncer could like put one hand palm facing down underneath his chin, and have his other hand punching it. nothing big, still small, discrete, and socially acceptable.
HAHA if it works out like this we could have a ginyu force type thing. awesome.
of course im going to be fairly obvious.
