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.

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."
