Slang term used in Philly to describe someone younger than you. Often times implying a possessive association with a preceding "My", when referring to a sibling or younger person who admires you.
If you are a young bol, then persons older than you are referred to as ol' heads.
You know that kid? Yeah, thats my young bol.
Did you see young bol dunk on that ol' head? Shit was crazy!
