Everybody got a bad side, let me see that shit
Cole is using the term ‘Bad’ in a complimentary manner referring to the woman’s back-side.
He ad-libs “drop” after he says “bad side”. In other words, drop and let me see that ass.
And it’s also a Nice/Bad reference keeping with the title “Mr. Nice Watch”
