look up any word, like potate: The sound that arises when you
step on a huge cockroach. It's technically the sound of the
roach's skin breaking under the pressure of it's innards being
forced outward by your shoe. This happens best with the huge
(German) cockroaches you see on warm summer nights in the
southern United States. Person 1: Did you hear that? Person 2:
What? Person 1: I stepped on that roach and it made a popping
sound! Person 2: Oh yeah that's roachpop. by lukeamotion June
