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."
Pretty sweet jump, but you dabbed your foot.
