Deriving from the use of the slang word "brozz" (singular "brozzle") for a persons "bro's", the phrase "brozzle nozzle" is a reference to the male member. Obvious as it looks, it is the nozzle, scientific term penis, on any particular brozzle, scientific term male, so to speak.
Example 1-
Person A-Can someone please explain a belt-tuck to that guy?
Person B-I know dude, his brozzle nozzle is raging out of control!
Example 2-
He better watch out mowing the lawn without pants-might get his brozzle nozzle caught in the blades...
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 "dimebroad" and then given the suffix "izzle" (or is "izzl-ized") in the tradition of E-40 and Snoop Doggy Dogg.
