May 27 Word of the Day
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"

The difference in personality that the presence of a female can cause in a male. A guy will do anything possible to cater for the girl, even if it means leaving the bros behind. It can often trigger increased aggression, funnel vision, lack of attentiveness and broken relationships with the mandem.
