To touch one's foot to the ground while bicycling. Considered to be a lost style point among trail riders, mountain bikers, bike polo players, among others. Since a lot of technical tricks can be avoided by simply walking the bike over a log or a stream, refraining from dabbing a foot encourages pure cycling and the attempt to negotiate obstacles by technical feats such as hopping or holding a track stand. Sometimes called a "foot down."

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."

A "dab" is when a cyclist touches the ground with his or her foot, shoe, etc. It is avoided in many disciplines such as mountain biking and trials riding.
