Flip, power move, jump with a rotation while airborne.
Flips entered breaking in the early-to-mid 1970s. DJ Smokey's Smoke-a-trons were known to execute flips , and presumably Grandmaster Flash's D-Squad member Flipping Mike did as well . Later, Beaver, Spy, and Trac 2 were known to do flips .
At some point, vocabulary from tricking began to influence flips in breaking.
