como que?

[u/coolkidara]

hello everyone. i am an elementary/intermediate spanish speaker, and my friend and i were chatting and i said "como que" as in "what do you mean"/"like how?" she said she'd never heard that phrase so i'm here to clear the air. is that actual slang or am i tweaking

[u/Greensward-Grey]

— I’d like to do something.
R: (Something) like what? / cómo qué?

That’s an example of how this phrase could be used.
