A "dab" is a popular dance move that involves bending one arm and extending the other while lowering the head into the bent arm. It became widely recognized in the mid-2010s, especially among young people and in hip-hop culture. The move is often used to express celebration or excitement. The dab is also associated with the Dabbing trend, which involves inhaling concentrated cannabis extracts. This method of consumption has gained popularity due to its potency and quick effects. However, it is important to note that the legality and health implications of dabbing vary by location and individual circumstances.
