hair band : n. , adj. : a rock band from the eighties whose members had long hair, which they teased up with hair-spray to make themselves out to be rebels and distinctive. the music tried to be hard and badass, but was harmless. this is sometimes used as a disparaging description, much like boy band is used today. he's the one they call doctor feelgood, he's the one that makes ya feel all right. new theme song for you all to jive with, been trying to get in touch with my inner hair-band.
