To wank proudly out of an open window and ejaculate onto the road or stunned passers by.

Bonus points for maintaining eye contact with a neighbour while slap boxing the one eyed champ!!
I'm in a rather dirty mood tonight Claude, infact I'm going to have a quick window wank. Should I ever need an alibi I'm pretty sure the neighbours will remember.
Get the window wank mug.
The act of jerking off outside a window whilst crying as the person commiting the act has come to terms with the fact that they are a pathetic welp of person who looks up vaguely sexual terms on Urban Dictionary to get a hard on, only to quickly be struck with the epiphany that they are wasting the precious life they have been endowed with, and the person you could have been has been burnt into nothingness by your abhorrent choices in life, and you are just the abysmal shell of what could have been a potentially good human being.

A wank window is limited time frame in which an opportunistic married man is alone in his home and can therefore peruse 'performing art' videos on the home computer whilst digitally stimulating his phallus. Mission control usually grants wank windows when the wife has gone to Tesco with the kids to do the shopping / gone to see relatives / went out with her mates. Wank windows are known to be tenuous and unpredictable because the wife may return early and the act of self flagellation may have to be aborted.
Courier: I tried to deliver the parcel to number 8 this morning but the bloke wouldn't answer the door. I rang the bell repeatedly but he appeared to be glued to his computer in the front room, ignorant twat!
Boss: How'd he look?
Courier: Funnily enough he was sweating, red faced and seemed utterly focused elsewhere.

Boss: Son, a man's wank window is sacred. When you're married you'll understand.
