Jukännit
When man or woman, drinks alone (supposedly) in a cruise-ship cabin, and suddenly sees someone in shower, drops his pants and slams his dick to the shover window and rubs it for couple of second and looks really mad same time., while winking to the innocent person in the shover.
There I was, doing shover and suddenly supposedly friend slams his dick to the window glass and starts winking at me, so get out of shover, we poor drinks and get wasted - Jukännit.
