Do random words just come to you when you need them and you know what they mean even though you didn't remember knowing them?

I think I know what you mean, and yeah. Sometimes a word just fits in the flow and then I'll think — where did that come from because I don't remember the last time, if any, I've used it.

I've even went to check to make sure it's being used correctly in the context, and it is.

I once cursed a dude out in Urdu for like 3 minutes straight.
I don’t speak Urdu. Lol
