Gunnitis

(n) a disease caught by those who attend Gunn High School, Palo Alto, and some surrounding schools. Symptoms generally start to appear junior year, though they may be present as early as sixth grade in some cases. Short-term effects include mad AP classes as well as extracurriculars, caffeine addiction, intense sleep-deprivation, a triple-booked schedule, no time for family and/or friends, and chronic talking online at 5AM while doing homework.

Long-term effects include acceptance to Stanford(in severe cases), heart disease, and a "BRING IT ON" mentality regarding life that will haunt you to your grave.

I was studying AP Biology while on a volunteer worksite in Canada over spring break and talking in French to my professor online, when I realized what a totally *Gunnitis* moment it was.

GUNNITIS

The weird emotional cocktail of feeling disgusted and amused at the same time, usually when watching something that’s supposed to be serious but ends up feeling goofy, cringe, or gross in a way that still makes you laugh.

Bro, I just saw that Superman 2025 teaser… I think I caught full-blown GUNNITIS."

"His take on Lex Luthor gave me GUNNITIS — I was disgusted but couldn’t stop laughing."

"Every time James Gunn throws in a random joke during a dramatic scene, my GUNNITIS flares up."

"That was so bad it was good. Peak GUNNITIS moment."
