The dab

completely dead

Dabbing (1) - Vaporizing concentrated marijuana, usually in the form of wax or hash, by placing it on an extremely hot metal object called a nail and inhaling the vapors produced. The nail is usually heated via blowtorch. Inhaling this harsh and concentrated form of marijuana often causes one to cry and wipe one's tears away while coughing and passing a bong.

Dabbing (2) - Performing the dance move characterized by raising an elbow and tucking one's head toward that elbow while raising and extending the opposite arm behind. This dance move is often seen while dabbing (1) since the dabber immediately coughs into his inner arm and wipes his or her tears away while passing a bong. See attached .gif image.

Evidence that humanity can evolve backwards

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."

Australian slang for dad.. also dabo

An internet trend where you sniff your armpit and think it's cool.

A new dace that's all the rage now a days. Made famous by some guy named Cam Newton. I think he's a golfer who won the Superbowl with the 1996 Bulls along side Michael Jackson. It looks like you are sneezing but you stick your other arm to the side like a sideways Nazi salute. This is referred to as Dabbing. The kids love to do it.
