A guy on YT actually tried it experimentally a few years ago (how many slaps, not how fast one slap); and it works to some degree! The main problem becomes to make a slapping machine that can survive long enough:

YouTube is truly a wonder of stupidity. Sometimes in good ways

This slap question was a big meme several years ago, and when that video came out (years after the meme), it was an instant hit.

The fact that this discussion is still going shows how popular it is

He also did a turkey a couple years after that for “slapsgiving”
