1. manipulative behaviour e.g. reverse psychology
2. predicting what will happen
Unfortunately, shitheads will sometimes mistake when a person is just simply predicting an unfortunate consequence due to a shithead's actions and accuse that person of "playing mind games."
See Mark McKinney from Kids in the Hall references to "mind games"
Hey man, don't play mind games, all right?
psycological tricks (reverse psychology, etc..) used to gain an advantage on one's adversary. Mind games can be used for casual situations like billiards or intense moments like convincing your boss/teacher that you were, in fact, on time. Invented in 2007 by Los Gatos Soccer head coach Rusty Millard. Not to be confused with Old Greg's "love games."
Rusty, " I was like, "Whatever Matt, I know you wanted to wear your green jersies, well you know what? It doesn't matter, we invented mind games""
Porter "We did not invent mind games Rusty"
Rusty "No, we did, last year"
