The act of extreme masturbation. You must "knock one out" whilst in close proximity to any of the following; Your mum, a nun, your boss, a member of parliament, George Michael. A person with capabilities to act upon catching you mid self-abuse obvisouly ups the ante. Ejaculation must be reached before your danger wank target comes (no pun intended) to investigate. The higher the chances of being discovered with one's pants down, pulling one's war face is obviously where the danger comes from. The more danger involved the harder (or softer) it is to complete the task in hand (snigger). The more dangerous the better. The chance of being arrested, pummeled by an angry father or having your hand severed by an arab's sabre means that you are a pro "Danger wanker."
"I was in my bedroom and i shouted downstairs, "Mum there's call the police there's a madman with a set of steak knives hacking me to pieces!" As soon as I heard her scream, I dropped my trousers and commenced the danger wank. As I heard her stomp up the stairs I knew i had to be quick so i upped the pace, i heard her stumble on the top step, which bought me some time. Unfortunately for me I timed my finish badly. As my mum barged through the door armed with a rollign pin I chugged all over her. I spent the evening in A&E with concusion. Now thats what i call extreme DW"

masturbating, but in such a way that you are very likely to get caught.
Increasing the thrill by trying to finish cranking one off before you are caught

While your jerking off, as your about to cum, shout down for your mother. The real game now begins, a race between you and your mum, you have to cum, clean up and pull up your pants before she enters the room.

a good timer is asking for a cup of tea before you start
Guy 1: "Dude, i tried a danger wank last night, it went horribly wrong"

Guy 2: "DDDDDuuuuuuuuuuuuuuudddddddddeeeeeeeeeeeeeee"

Guy 1: "No, it's ok, she helped finish me off"

When you masturbate quickly with a good risk of being caught so it's more exciting.
I was upstairs earlier and my cleaner was dusting downstairs so I had a danger wank while peeping through a crack in the door at her

The act of having a wank, and calling your mum just before coming. Then coming, and cleaning up before she walks into your room.
