alright, i know most of yaw are probably thinking im an idiot to think its a bay slang since most ppl often say "ay" when they hollar @ someone except folks in the eastcoast who say "yo". but i didnt mean it in that form, but like before a mc raps. i noticed alot of cats from the bay start out with an "ay, ay, ay" then they spit. ya boy, clyde carson, & johnny ca$h are some ive notice does that alot.
