What does it mean when a guy says wyo?

I'm curious, could you elaborate on what someone might mean when they say "wyo"? Is it a common slang term or perhaps an abbreviation for something specific? I'm not familiar with it in the context of cryptocurrency or finance, so I'm wondering if it's a term used in a different field or perhaps a regional expression. Clarifying its meaning would help me better understand the context in which it's being used.
