When a small group of people make up a joke (a phrase) while no one else is there (Sometimes because of an event that occurs, and then someone says something and it becomes an inside joke) and don't tell anyone about it, so every time anyone (whether from the group or not) says the phrase, they all start laughing like idiots for an unknown reason. It completely baffles people outside this group why it would be remotely funny. Most of the time it confuses them, or annoys the crap out of them.
Jeff started cracking up for no reason when I said "jelly"

Get the Inside Jokemug. A Liam Joke is a joke that is intended to be funny, but is rather painfully unfunny and beyond generic. The origin of the phrase “Liam Joke” comes from Liam Griffiths (Born January 13, 1999) who constantly uses the joke “Guess what? Chicken butt” when interacting with his family.
PlayerColton2k: Guess what?
Big B: What?
PlayerColton2k: Chicken butt
Big B: Wow, I’m pissing my pants so hard. You just told a Liam Joke.
PlayerColton2k: What’s a Liam Joke?
Big B: A joke that’s not funny.
Big B: What?
PlayerColton2k: Chicken butt
Big B: Wow, I’m pissing my pants so hard. You just told a Liam Joke.

Get the A whole jokemug. When an Ash Joke is made, most of the room appreciate the incredibly clever, often witty, nature of the joke. The joke can often go over less clever people’s heads, creating the illusion the person who created the Ash Joke is stupid. This could not be further from the truth. The Ash Joke joker can remain smug at the fact that the stupid people therefore think that they are stupid. The irony.
Damn, the guy at work made an Ash Joke and I was the only one that appreciated it. The rest thought he was stupid but in fact they are the stupid ones.
That guy is either stupid or he just made an Ash Joke.
