I've stumbled upon a very peculiar phrase in a comic I'm currently reading; here's the screenshot.
As can be seen, just before exiting the train some gangsta guy quips "Sixty tray, all day" to a young woman.
What does he mean, exactly?
As far as my poor knowledge of the gangsta slang permits, I suppose that "tray" has something to do with "three" — but then again, what's a "sixty-three"? Is it a quantity of something, or a sexual position, or a widely-known chapter of some penal code? I'm at my wit's end.
Trying to google the phrase in search of context leads me nowhere, for all exact quotes refer to the comic itself.
