The noise beatboxers use when imitating the sound of the discs being scratched on turntables. Can also be used in the same way as such words tru and legit; as an agreeable statement, or instead of sup or what it is; as a greeting.
G#1: "aight man, lay down the beat."
G#2: "(beatbox sounds) erra! (beatbox sounds)"

girl1: "ah man, last night was so liveee!"
