Also classic astroturfing is complaining about astroturfing. Fact is you never know who posts a comment. But mostly, I agree with your sentiment here.

Cool! What part did you learn??

Update: my hand hurts now, but in fact it is possible to lay down a pinky, then snap three times successively with ring, middle, then index, which makes three different snaps (descending in pitch).

I gotta say, surprised everyone is attributing the “snap” sound to hitting the pad of your thumb.

All y’all veteran snappers, try this. Lift up your pinky, then snap. Makes a much higher pitched snap. Now lift up your ring finger, then snap. No snap at all. Your pinky and ring finger make a sort of tube, and your thumb is striking one end of it (the crevice between thumb pad and ring finger tip) to make a tone. I’m even able to smack that spot with a finger on the OTHER hand and make a (quieter) snap.

Hope this helps.
