To "flip his mix" - Derived from the accidental flipping of a large bong mix, combined with the tradition expression, to "flip his lid."
"Man dem gonna flip his mix if he don't calm down blud," and, "Last night my girlfriend proper flipped her mix at me." Or, "What, you think you could flip my mix?" or, "This is some proper mix flipping shit man." "Chill bro, don't flip your mix."
