When one swerves accidentally and tries to make the accidental swerve look purposeful to avoid detection for being a bad driver, stoopid, or drunk. A swerpose starts as a little drifting to one side or another, usually on the highway. The driver, realizing that he or she is swerving and looks drunk or high, just goes ahead and changes lanes trying to make it look purposeful, when it really isn't.

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."
