1) Used when the word "Sayin" cannot bare witness to the flyness.
2) Also used as a form of "Hello". Derivative from colloquialisms that incorporate questions into greeting such as "How are you?" and "Sup?".
1) Smithy's got bare weed if you see what I'm sezin'?
2) Me- "How are you?"
You- "Safe. What you sezin'?"
