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."
