Worst insult on this site is...

Especially when delivered by somebody about three rating points higher.
Lol - yeah as if three rating points means anything in online chess (just three? Even OTB chess three points means close to nothing).
On a more serious note though. I disagree that "at your level" is intrinsically an insult to a chess player; I will however, agree that it is often used in an arrogant way. Everyone wants the chess rating to stand for an unchanging status or milestone - unfortunately chess ratings constantly fluctuate. Even 100 or 200 rating points means little - especially online. "At your level" is certainly used insultingly by many, but that says more about the person than the wording; "at your level" does not always mean insulting.
For example: blueemu, "at your level" of chess, I won't perform that well - yet I am trying to improve and I hope I can soon reach that level

My rating is a joke. It's largely based on two good wins at a Glicko RD of over 200.
To be honest, they WERE good wins, though. Check my "Kids, don't try this at home" thread.
By the way, I usually say "At our level..."

At your level, I'm not sure you're prepared to understand the intricacies of insults. Stick to 1.e4 for now.

I did check that thread a while ago - it was a pretty good game
At your level.
Are you really offended by this?
Depends on the position

Not on the site but irl:
It is when you lose to THAT guy who is slightly better than you (but is that really the case?), and after he won, in post analysis says you were DOOMED in this specific position.
At your level.
