If your planning on being a chess hustler that talks smack... you've already failed the part that consists of talking smack.
What is the perfect chess insult?

I only play with friends and family over the board, but one that never gets old is "maybe you should take up checkers".

Years ago, I had a co-worker that liked to listen to rap and hip hop...
One day I was surfing youtube and "Your mama is.." battle waa trending, and I remembered one insult that I that was really funny, so the next day I mentioned it to my co-worker...
He went on a 5 minute "your mama is.." bender that had me laughing so hard I waa getting a cramp in my gut.
After it was over I asked where he learned all those insults, and said he just made them up on the fly.■

I had a subtle thing, that struck me the most. He must have been a master of breaching psyche. My position was understandably worse, and after a mistake he wrote in the chat (while executing his solution) "Why did you made that move?.." ... (_ _)。I remember I was devastated by it.

It was either A.Nimzovitch or R.Spielman once stood up during a tournament game and shouted across the room 'why must i lose to this idiot?'

“Keep the change, ya filthy animal!”
When they respond negatively to it, I reply:
“Hey, chill out! It’s just a quote from one of the most famous Christmas movies of all time, ‘Home Alone.’ I just like spreading this cheerful message year around.”
And then I add at the end:
“Now don’t forget: “keep the change, YA FILTHY ANIMAL!!!!”
And some of them STILL get annoyed. Even though they now know it’s just a cheerful message. Hilarious. 😂
Between moves, I like to chat up my opponent to distract them from the game. What are your favourite lines to use?
