Locking is a style of funk dance, which is today also associated with hip hop. The name is based on the concept of locking movements, which means freezing from a fast movement and "locking" in a certain position, holding that position for a short while and then continuing at the same speed as before. It relies on fast and distinct arm and hand movements combined with more relaxed hips and legs. The movements are generally large and exaggerated, and often very rhythmic and tightly synced with the music. Locking is performance oriented, often interacting with the audience by smiling or giving them a high five, and some moves are quite comical.

Locking was originally danced to traditional funk music, such as that produced or performed by James Brown. Funk music is still commonly favored by locking dancers and used by many competitions such as the locking divisions of Juste Debout and Summer Dance Forever. Locking movements create a strong contrast towards the many fast moves that are otherwise performed quite continuously, combined with mime style performance and acting and other dancers. Locking includes many acrobatics and physically demanding moves, such as landing on one's knees and the split. These moves often require knee protection.
