I have a sentence in bold:

Rajesh: You know who's got to be the bravest person in the Marvel Universe? Whoever has to give She-Hulk a bikini wax. Howard: You want to talk brave, how about Captain America's undocumented Mexican gardener?

I am pretty sure that it doesn't mean "You want to talk in a brave manner". I think it means "Do you want to talk about brave"? But what does BRAVE mean here? Does it mean A BRAVE MAN or BRAVERY or BRAVE PEOPLE? I am not sure. I also would like to know whether it is possible to use other adjectives with TO TALK in the same way.

I would like to talk happy (about happy people????) I would like to talk rich (About rich people????)

What do you say?
