Well I, for one, have NEVER piddled! I've urinated, micturated, peed, pissed, passed water, took a leak, drained the lizard, and pointed Percy at the porcelain. When I was young I pee-peed, tee-teed or wee-weed, depending on whose house I happened to be in at the time. I've also fired a few rounds from the heat-seaking moisture missile, though I'm not sure that's the same thing. But piddled? Nope.
