"Kebabs, fruit machines, and brasses" -- what do these slang words mean?

A kebab is a type of fast food; in the UK it's often associated with post-pub eating.

A fruit machine is a gambling device; in the UK you can often find one in a pub.

"Brass" in this context puzzles me, but Wiktionary suggests (see "Translations") that it can be a slang term for a prostitute. That seems the most likely interpretation of the ones I can find.

To add to Peter's answer, with the parts he did not cover.

The "spunk your wages" bit, spunk means ejaculate, it's an odd phrase, but people often say "blow your wages", meaning spend them quickly, waste them on nothing. "blow your load" also means ejaculate, so it is an easy crossover.

Cockney Rhyme: "Brass Band" rhymes with "hand." He's referring to a handjob from a brothel or massage parlor.

The first two aren't slang terms; only the third is.

1. Kebab means meat cooked on a skewer, generally from the Eastern Mediterranean.
2. A fruit machine is a gambling machine, they used to be called one armed bandits.
3. Brasses is a slang term and means prostitute.
