I think I can parse the style you're talking about. It birthed in Joss Whedon pop culture (e.g., Buffy the Vampire Slayer).
Imagine 2 people at a bar:
A - Got in a fight yesterday.
B - Those battles'll kill ya!
A - Girl dumped me after that.
B - I had a date with an elf once, but she was actually from Finland.
A - That's what they say about women.
It's quotable dialogue, but AT each other, with no character or world dev in it.
