Yellowposting

Yellowposting is a movement by 4chan's /b/ board to stop the spread of pornography on the board. It is commonly seen as users posting images with a bright yellow background, reasoning why pornography is bad and shouldn't be spammed throughout the board.

Anon1: *furiously masturbating to random porn he found on /b/*
Anon2: Fuck porn, porn is for porn boards, not /b/. *Continues Yellowposting*

Yellowpilled

Like being redpilled. You reject the dominant socialist worldview and accept free market capitalist ideas.

I used to be a commie but reading Mises yellowpilled me.

Yelloum

A versatile, multi-purpose word that shifts meaning depending on context or vibe. Yelloum can be a greeting (“yelloum, babe”), an exclamation, a filler, an inside-joke adjective, or simply a mood. It carries the energy you give it—warm, chaotic, affectionate, dramatic, or just unserious.

“Yelloum, bestie, what’s going on?”

“That outfit is very yelloum.”

“Yelloum!!!”
