Also known as DTRD, Dissociative Temple Run Disorder occurs when you've been playing the game Temple Run for so long that you misjudge how long you've been running during that round.
Dan: "What?! I thought I was so far down the course but I've only run 2,000!"
Margaret: "Whoa, take a chill. It looks like you've got yourself some Dissociative Temple Run Disorder. You may need to take a break, you've been playing for two hours straight."
