k0: I am going to play scissors.
k1: I know Bob usually plays paper, so I'm going to play scissors.
k2: Bob knows I usually play rock, so he will play paper, and to beat him I will play scissors.
k3: Bob is aware that that I know he usually plays scissors, and that I'll play rock to beat him, so he will play paper. To beat that, I will play scissors.
etc.

1: What the hell? The highway was completely jammed yesterday, but the second I think to come take this shortcut, the highway's empty, and the damn shortcut is jammed!

To change a thought or view when it suits the person. Used by people who don't want to admit to being wrong but not realising that it shows weakness on their part.
An example of flip flop thinking:
"I voted for the reds in the recent election because they're the best party."
*Blues win election*
"I knew the blues would win - that's why I voted for them!"
"I voted for the reds in the recent election because they're the best party."

Why would I think it? Why would they insinuate it? Why would they feel entitled to getting away with it? If I were to do and/or insinuate that I would do a thing to a retard, would you feel contempt for for me if I felt entiled to getting away with it?
Hym "I think you would. I think if I insinuated that I would do a thing you thought was wrong you would try to punish me. Or at least insinuate that you would punish me for my insinuation. So.... Sorry, I guess. I know my shoes are a little soggy. It precipitates a lot where I live. Try not to get a rash..."
