When a guy curls up into a ball and then proceeds to pull a Durex X-tra Strentgh Condom over his entire body.
He will stay within the condom for the next week, while occasionally discharging bodily fluids. The mixture of shit and cum are evenly distributed all throughout the condom, enclosing the man in a chrysalis of sorts. After the 7 day period, the guy then bursts out of the condom and flies away with his newly developed butterfly wings.
Ah, the beauty of nature.

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"
