Mumu

Mumu, also spelled Moomoo, is the green cartoon bull that personifies a bull market on 4chan's /biz/ board1. He first appeared in July 2018 as a counterpart to the bear character Bobo and stuck around as a /biz/ staple long after2. Mumu later inspired a 2023 Ethereum memecoin called Mumu the Bull ($BULL)1.

Overview

Mumu, also written Moomoo, is the cartoon bull that personifies a bull market, the trading term for a stretch of rising prices1. The crypto and trading community treats him as the mascot of the bull run, a role dating back to 20181. He's drawn in the wobbly MS Paint style of Apu Apustaja, the same base behind many of /biz/'s finance characters3.

Mumu's identity is built around his rival Bobo, the bear who stands for falling prices, and the pair are framed as locked in an endless struggle over where the market heads next3. A third character, Snibs, joined later to represent a flat, sideways 'crab' market4. Together Bobo, Mumu and Snibs make up the trio /biz/ uses to read the market's mood4.

How It Spread

Through 2018 and the years after, Mumu settled in as /biz/'s go-to bull reaction, posted opposite Bobo whenever sentiment flipped. A third figure, Snibs, arrived on March 16, 2019, to cover the sideways 'crab' market. His official name was voted as Penny Pincher, but Snibs held on, the same way Mumu beat Bevo.

Mumu's reach extends across the wider financial trading community, which uses the bull as shorthand for a market on the rise. On November 11, 2023, an ERC20 memecoin named Mumu the Bull ($BULL) launched on Ethereum as a tribute to the character. The token shipped with a fixed supply of 100 trillion tokens and a 1% transaction tax set aside for marketing.

The word 'mumu' carries unrelated meanings outside finance, including a loose dress and, in some Central European slang, a crude term. Those senses predate the bull meme and have no connection to it.

How to Use This Meme

Mumu typically works as a reaction image. Posters commonly drop him into /biz/ threads when prices are pumping or when they want to project bullish confidence, often contrasting him with Bobo when sentiment turns. A common convention is the back-and-forth format where Mumu and Bobo trade wins as the market swings, a setup that started on 4chan and traveled with the character.
