John Redcorn

A Native American middle-aged man who makes raunchy and self-fetishizing posts for clout on social media, to attract unsuspecting women. They typically are narcissists with no shame, putting it all out there, and do not care to portray harmful stereotypes. They are the fantasy of every white lady who watched "Dances with Wolves", and think that could be them, except John Redcorn's are womanizers and not looking for anything serious.

It's a reference to John Redcorn a Puebloan, who was the lover of Nancy Gribble and father of their love child, Joseph, in the animated series "King of the Hill".
Kuiahuitl on TikTok is always posting thirst traps for the white gaze, he's such a John Redcorn.

Did you see the latest @Modern_Warrior scandal? He's been womanizing like a real John Redcorn, and even worse for years!

Hey! Leave those white women alone, Stop being a John Redcorn and settle with a nice girl!

John Redcorn

1. A character from King of the Hill. He is of the Anasazi Native American tribe which he proclaims once owned half of Arlen and wears it proudly sporting long hair, a traditional vest made of some sort of hide and a thick accent, even incorporating it into his profession as a traditional, holistic healer.

He is very popular, somewhat shy, doesn't speak much and is considered physically attractive by many in Arlen. In his past he was the lead singer of the band Big Mountain Fudgecake. In spite of his pride, he keeps his romantic life private and seems to prefer adultery with married women, including an on-again-off-again affair with the frequently seen Nancy Gribble. He has at least two bastard children: a son Joseph Gribble (whom he doesn't seem to support at all!) with Nancy Gribble and a daughter named Kate from a relationship with a woman named Charlene who he apparently met while she was some kind of stripper (this is what is implied), both teenagers (and both seemingly exhibiting symptoms of psychosis).

There is a running gag about how almost everyone in Arlen knows Joseph to be his biological son, but Dale Gribble, who Redcorn at times pretends to be friends with, for all of his paranoia, suspicion and conspiracy theories can't apparently piece together that he ISN'T Joseph's father (in spite of the obvious and impossible physical differences and his access to DNA testing) and that his neighbors best friends actually do know something he doesn't, and it has nothing to do with aliens! Interestingly also, in spite of how mean-spirited Kahn Souphanousinphone and his wife Minh Souphanousinphone often are, they haven't tried to spill the beans about this.

2. A sneaky, shameful man, particularly one who sleeps around having bastard babies with foolish women and tries to hide them after the fact.
1. You redcorn! If you're gonna have an affair and make a baby, you're gonna take of it, or I'll let all of Texas know what kind of "strong indian" man you really are!

2. Ya livin a double life? You musta lost yo mind, John Redcorn!

3. A good way to make a show (or rl) interesting and suspenseful is to add a John Redcorn.

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
