You’re impossible to underestimate
It only really works if somebody else starts it, but my personal favorite is “No you”
No matter what they throw at you, you always have something to say.

I mostly use it in game chat, and one time I got someone so frustrated that they could not top me that they rage quit.
Whoever told you to be yourself simply couldn’t have given you worse advice.
