A reference to a woman who is a "10" (on a scale of 1-10) and thus very attractive. It's important to note it's derived from "dime broad" and then given the suffix "izzle" (or is "izzl-ized") in the tradition of E-40 and Snoop Doggy Dogg.
I came up on a serious dime-brizzle at the spot last night.
A Dime (perfect 10) Breezy with the E-40 suffix (izzle) added to it.
That Dime-Brizzle by the bar's been eyeing me.
