when you are having a conversation and this of the most perfect word to describe what you're talking about, and suddenly the word escapes your mind, and you spend a good 10+ minutes trying to remember the word. then out of nowhere the word comes back to you, your hands grip whatever is in arm-length and you let out a gasp.
"yeah my parents got married a lot later, but theyre quite.....crap i just had the perfect word"
"what was it"
"it had to do with uncommon, or against society"
(10+ minutes later)

What happens when you think more than you're accustomed to without properly stretching your brain first. Can result in serious brain pain and possibly permanent brain malfunction. Can be caused by overstudying, overthinking, overphilosophizing, and the chronic use of hallucinogens, which can decrease brain function and thus make an accidental sprain more likely.
Person: I've got my calculus class at 7am tomorrow...aauughh....
Friend: Oh yeah, I took that one last semester. I got a sprained brain from it, make sure you stretch before class.
Person: ...how...do you stretch your brain?
Friend: I dunno, but it gives you an interesting visual, doesn't it?
