What's goodybags?

A phrase used as a sign of weakness, in place of "what's good" most commonly used by teenage bros that wear bro flops and are perk heads/coke addicts/drug dealers etc... if a bro is approached by kids that want to beat up him or whatever friend that is in house he will come to the door and say "what's goodybags?" to appear cool and calm... but little does he know, jo beat up dom
