Now, I'm not as much of a grammar nerd as I'd like to be, but from what I understand, "irony right there" isn't a complete sentence, or barely even a complete clause. It's just a few words that should be part of a clause.
Maybe someone could fill in the grammatical details here, or prove me wrong.
Yes β exactly! I think that's actually the missing part here: "That's". It makes the following thing they say sound much more complete. π Thank you!
