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]
Don't Bring Me Down A common mondegreen in the song is the perception that, following the title line, Lynne shouts "Bruce!". In the liner notes of the ELO compilation Flashback and elsewhere, Lynne has explained that he is singing a made-up word, "Grooss," which some have suggested sounds like the German expression "Gruß." After the song's release, so many people had misinterpreted the word as "Bruce" that Lynne actually began to sing the word as "Bruce" for fun at live shows.[5][6]
