trey

What does trey mean?

The number 3, which the Black Disciples claim as their number. That's why BD sets stack it — 300 (the O'Block movement), 051 Melly Mob, the triple-i stylings in names like WiiiC. If a Chicago rapper is throwing up three fingers or repping 'trey-side,' they're flagging BD.

"Three fingers up the whole video — pure trey, pure BD."

Origin

From 'trey' meaning three (as in cards/dice).
