I suppose I'm a jiggler, but there's hip action, and it really takes more of a up-down-side-side motion, kind of like I'm a priest walking up and down the aisle of church blessing everybody with holy water (not picking on priests, but just giving you the idea).
But, I never really thought about it, since I am too busy staring at the flush handle of the urinal. My trick to get over the bashful kidney I had when I was younger, was to stare at the printing on the top of the chrome parts and focus on the words like a mantra - "Ah, Zurn. Zuuuurrrrrnnnnn...."
And don't get me started on those funky auto-flush sensors. It freaks me out to think that there are people staring back at me, waiting for me to finish and do my hula dance, so they can flush the thing for me..
