If you're in a public toilet, like the one at your local gym or leisure centre (sure, because fat slobs with the time to read this crap regularly exercise), have a little fun. Go into the cubicle, whip "it" out and begin to pee. But move around. Swing your hips through a circular Mickey J motion. Let the pee go here and there, splashing around the pan, and if you're naughty, perhaps even the toilet seat!
Begin to take control of your penis (or funnel, gals)...grab it, and shake it from side to side, so that only about a third of the pee goes in the toilet. Now begin to wiggle it up as well, thus peeing over the walls. Bring it down and pee on the floor.
Your next target - see that little white container screwed to the cubicle wall holding the toilet paper? Give that a wee scoot. This way, the next guy who comes in will have a crisis on his hands, quite literally. He will either sit down to drop a jobby, or he'll stand up to do a piss. Either way, unless he's some sort of clatty bastard, the chances are he will need toilet paper at some point. But if you've done your business all over the inside of the toilet-paper-holder, then he wont realise it's covered in your urine until he's reached his hand in. Touch my piss, you asshole!
It would also be a good idea to pee on the toilet flusher, thus the chances of the next user touching your piss increase. Unless it's on a train, because let's face it, nobody seems to flush their doings away while using the railway service.
So remember kids: pee on the cistern, the seat, around the rim, the floor and wall. If you're really feeling mischevious, wait until some loser enters the cubicle next to you and lob some urine over the seperating wall in his direction. Dream situations include insects creeping around the floor. Watch them and laugh as they're whisked off by your pee-pee jet, completely at your mercy. Try it. And if you're one of those soppy sack of shits that will end up feeling guilty about the cleaner, sit down and piss like the girl you are.
