When you are about to give someone a high five, right before the hands touch, you turn the wrist of the raised arm
90 degrees, mimicking an
air vent opening up. This causes the recipient of the prank to miss the high five and stumble forward under his own momentum as you walk away proud.
For the two handed
high five, the double air vent typically results in a hug.
guy- "watch out this guy high fives really hard dude"
you- "ok, noted. check this out"
(successful
air vent. kid on ground)
guy- "wow, i've never seen anyone
trip up so hard! You
vented him like a champ."
