A word retarded coke dealers text you at 5 in the goddamn morning to see if you want to buy drugs. They for some reason think you know what it means even though nobody knows what it means especially not you. Because even though you snort occasionally you're not a lifeless fuckwat and you have a job and want some motherfucking sleep.
It means "how are you?" or "what's up?" A funny way to express that everything is good by referencing wealthy lifestyle with the expensive fashion brand in the expression.
