That's basically how nondescriptive rp works!

There's more! Check the rest.

Here is an example.
Rp -
??? : What do you mean!? (add *[Action]* Here if you want)
*??? Face palms* (<--- don't do if you add the action to the oc / you talking)
??? : I told you never to say that!

Ah okay thank you! I'll try my best!

And if you need to do ooc aka out of context. You can do.
() [] {}
