Keyboard Theory

When suddenly everybody wants to play with a toy or item (like a keyboard) that has been buried under the bed or tucked away in a closet for years.
Raul: I found this keyboard under the bed. I'm gonna learn how to play the Star Wars theme on it.
Brock: Hey! Gimme that! It's mine!!!
Raul: It's been collecting dust under the bed for 5 years and now suddenly you want to play it? That's Keyboard Theory.

Group Chat Theory

Group Chat Theory is the unofficial theory that all big non-work group chats follow a set structure:

1. A group chat is created that’s just you and your close friends for actual discussion and funny conversations, and all is well and good

2. Your friend eventually insists on adding their friends that you either don’t know or don’t like, but they’re eventually added in, even if you do try to prevent it

3. Those friends either immediately cause chaos, or will just start adding THEIR friends too. Now the group chat is full of randos that are 99% of the time unfunny rude dickheads.

4. Those randos then quickly devolve the chat into the following:

- Bulling someone
- Arguing about beef between each other you either don’t know or don’t care about
- Fill the chat with shitposts instead of actual discussion
- Spam unfunny and illegal shit like gore, porn, drug dealing or more cause they think it’s cool. This then leads to a “Group Chat got leaked…” situation, where the group chat gets leaked to the police or the public, and said unfunny, criminal randos either run away and escape, inevitably to cause another Group Chat Theory in the future, or get caught by authorities and arrested.

5. All of this continues until the group chat meets its metaphorical breaking point, and is either abandoned (otherwise known as a “Dead chat”) or deleted by the owners/taken down by the police.
“Bro that group chat fell off, everybody’s just being a dickhead on there, we should create a new one

“Yeah bro, that’s literally Group Chat Theory”

Jesse what the fuck are you talking about.”

Mental theory

An easier way to say Theory of mind.
In psychology, mental theory refers to the capacity to understand other people by ascribing mental states to them. This includes the knowledge that others' mental states may be different from one's own states and include beliefs, desires, intentions, emotions, and thoughts. Possessing a functional theory of mind is considered crucial for success in everyday human social interactions. People use such a theory when analyzing, judging, and inferring others' behaviors. The discovery and development of mental theory primarily came from studies done with animals and infants. Factors including drug and alcohol consumption, language development, cognitive delays, age, and culture can affect a person's capacity to display theory of mind.
Dude has no mental theory, he really thinks I don't know this.
