If you notice the timing on the one video the guy in the center starts falling before the "technique". My BS detector went into orbit. I also noticed one attacker did not fall down and the guy pushed him down-oops. Forgot is cue card.
Perhaps there is merit: halitosis, garlic, nasty teeth, or bean aura.
Perhaps we should have a redbuttbeano.com. After a hard night of bean burritos as the attacker runs your turn tail-well need I say more.
