Things some chess players say when they blunder

Good game...fancy a rematch, for lets say, 10 dollars?
I dare you to take it...you know you want to...
Are we playing touch move?
What are you doing?! You can't move twice in a row!
Could you please hurry, I'm late for an appointment...(translation: dont take the piece, I hate disappointment)
I was distracted by your inability to write English competently!
so what should i cry a river now or stop speaking?

I could have trounced you easily in that middlegame. But I know how fragile you are! And I didn't want to burden my conscience with the guilt of crushing you.

I didn't see this classic from the Fischer vs. Spassky match: "IT'S THE CAMERAS!!!!!!" -Fischer, well, sort of.
Another one might be the Soviets insisiting that Fischer had something in his chair, but I don't think that was Spassky's idea.

Or what about Kortchnoi saying the Soviets were passing Karpov secret messages in his yogurt? That was classic!

Lol just found this one on Wikipedia
1957, (Botvinik) lost to Smyslov by 9½–12½ in Moscow,[43] but the rules then in force allowed him a rematch without having to go through the Candidates' Tournament, and in 1958 he won the rematch in Moscow;[44]Smyslov said his health was poor during the return match.
See?? Even Grandmasters do it!
When I make a blunder I admit it and resign, if needed. It happens to me often when I think of my super beautiful girlfriend and can not help to make mistakes. Follow my advice, chess players of the world: accept your mistakes and you will be at least 1/2 as happy as I am.

I was trying out something new
I wanted to see if you were paying attention
I misclicked
I touched the piece by mistake so I had to move it
I would never make that move if I wasn't so low on time
That bishop was on the dark square!
You didn't beat me, I beat myself
I haven't eaten anything all day...I can't concentrate when I'm hungry
You know what they say, "________" (Insert irrelevant quote about the best man not always winning here)
I have a habit of playing down to my competition
i always say you played so bad i couldnt take any of your moves serious and thats why i blundered.
Actually i was just joking, somehow i feel im always playing much stronger players that give me chances
