A spin is a b-boying move that involves rotation of the breaker's body about some axis in contact with the ground. It is possible to perform a spin on virtually any part of the body, but bare skin often causes painful and spin-killing friction with the floor. To solve this problem, many breakers employ pieces of cloth or wear long clothing, pads, or caps. When the dancer uses his hands to aid in speeding up the spin, it is called tapping. A dancer may tap for a few rotations and then glide for subsequent rotations. Spins form an integral part of many breakers' routines, while others eschew them in favor of more complex-looking repeated movements, back and forth, after each rotation in a given direction.
