A thing that gangsters in the UK (Roadmen) say to you when they are planning to do some disrespectful shit to you, it can range from a simple beating and robbery to a cheffing.
Roadman: Ay, what you got for me, fam?
Innocent pedestrian: Nah, I don't have anything on me.
Roadman: Stop playing with me, man.
Innocent pedestrian: I swear! Just leave me alone!
Roadman: Come round the corner fam yeah I've had enough of you.
