Brass razoo

Okay, imagine you have two coins in your pocket. One is shiny and silver while the other one is dull and brownish-gold. The dull and brownish-gold one is called brass razoo.

Now, brass razoo is basically an expression that means you don't have much money. So, if someone says "I don't have a brass razoo," what they're saying is that they don't have any money at all.

It's kind of like how you might say "I don't have a single penny," when you don't have any money either.

So, remember, brass razoo just means you don't have much money, and it's not really a coin you can spend.
