where does the expression drop the mic come from
Mic drop The gesture dates to the 1980s when it was used by rappers and comedians. Performers from both groups can engage in confrontational performance styles - rappers may participate in rap battles, comedians may interact with a heckler in the audience - and dropping the microphone after a particularly effective line indicated complete confidence in the opponent's inability to come back with anything that would be worthy of a response. An early occurrence was Eddie Murphy in 1983 in his standup show Delirious.[2]
Sound of da Police The song begins with KRS-One whooping twice to evoke a police siren (the "sound of the police"); this recurs several times throughout the song. The heavy bass sample loop was taken from Grand Funk Railroad's cover of Inside-Looking Out, the final track of their LP Grand Funk.
