Tubbocore

Tubbocore was originally a joke aesthetic that revolved around well-known Minecraft Streamer Tubbo.
It started as an inside joke in a Twitter group chat called, "sgwgc" on July 30th, 2021, but soon largely spread to be well-known by many and is no longer an inside joke. Some even seriously use the aesthetic for edits and other things.

Person 1: Do you like Tubbocore?
Person 2: Omg yes! The aesthetic is so pretty, just like Tubbo!
Person 1: Agreed! I love it too! We should make a Tubbocore edit together!

Person 2: Omg totally!

It's like hardcore, except even faster.

A: "So what will you be doing today?"

B: "Nothing fun, just working turbocore"
