k0 thinking 

Originates from game theory, (the field of math, not the Youtube channel.) The 0 is replaceable with any number, usually no higher than k1. Describes how many "levels" of thinking someone exhibits.

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!
2: What the hell kind of k0 thinking is that man? Did you not think about how everyone else ALSO knows about this shortcut?
