In middle school this male troper knew a rather obnoxious variety of this. She would call me a crybaby whenever she caught me crying in the slightest, no matter how much I tried to hide it... when catching me talking to myself she would be all like "oh look the crybaby guy is talking to his imaginary friends now." She even spread false rumours about me, and defended them by saying
"well if they weren't true you wouldn't be getting all defensive now would you?" And so, I am not fond of the idea of associating snarkiness with intelligence, especially with how ridiculous the logic of some of her snarking was. (On a sidenote, she was
rumoured to have a crush on me, though I never got to see her reactions to that rumour, and if it were true then that is a horrible approach to take to hiding OR expressing it.)
