Crank

When a male relieves himselfin the lavatory with some double pleasure on the potty.... ie. A Crap! A Poop! A Number 2!! & A Wank! A Toss! or A Pull! These will be timed to occur simultaneously to pleasure him in the loo. Yikes

Bloke get's up at smoko on building site and announces "I am off for a crank!" Has a pull and a poo for fun!! (yeah kids, im a little grossed out too)
