Da artery in yer neck dat enables you to toss several objects up in da air and then rhythmically/successively catch them and toss them back up again, without dropping them or having them hit da floor.
My juggler vein doesn't seem to allow me to be very proficient at manipulatingtennis balls in midair, so I just stick to performing "palm-juggle" wif da soft warm slender hands of cute chicks whom I befriend.
That moment you have in a bathroom when you take a shit but since people enter in and out of the bathroom, you need to drop it at just the right moment in between their visits.
Stephen: Dude Alex is such a good Crap Juggler! He is able to shit when like 7 people entered the bathroom within 5 minutes!
