A term mentioned in Cobra Starship's "It's Amateur Night At Apollo Creed!" in the line "I love, love girls with Brooklyn haircuts". In an interview Ryland Blackinton gave during the Really, Really, Ridiculously Good Looking tour, he explained that the term is derived from the "scenesters" that reside in Brooklyn and the haircut in question is infact a "scene" cut. Choppy layers, side swept bangs, go visit a local show for real life examples.
For examples of a brooklyn haircut, go see one of the following bands and take a good look at the haircut the majority of the girls will be sporting:
Cobra Starship, We The Kings, All Time Low, The Academy Is..., The Audition, Fall Out Boy, My Chemical Romance, Forever The Sickest Kids, Mayday Parade, etc.
