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]
Taking the piss "Take the mickey" may be an abbreviated form of the Cockney rhyming slang "take the Mickey Bliss",[8] a euphemism for "take the piss." It has also been suggested that "mickey" is a contraction of "micturition,"[6] in which case "take the micturition" would be a synonymous euphemism for "take the piss." The phrase has been noted since the 1930s.
