a dance where you wave your arms like a bird's wings.....but if you think it originated with some generic jive-ass bay area gangsta rapper, i sincerely hope a seagull shits on you. it originated with The Time, in the song "The Bird", from the film "Purple Rain". in 1984. and y'all know the Wright Brothers can't fuck with that.
"America...have you heard? I got a brand new dance, and it's called the bird"
