Definition: A figure skating spin maneuver wherein the skater maintains a layback position while holding their free blade up to but not above his head and then pulling it in closer to his head. The skater would then lean their head back into the skate as if getting a “haircut”.
“She gracefully bends her back and pulls off an elegant haircutter.”
