Noun: an archaic device common to British railway station restrooms until the 1960's. The Pisswangle consists of wooden rollers turned by a crank operated by the Pisswangler or Pisswangle operator. The male genatalia is passed through the wangle thus squeezing out the last few drops of urine and preventing seepage into the pants.
"Lord Thistlewick hated dribbles of urine in his pants and always tipped the gent's room pisswangler at Victoria station handsomely."
