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: What’s a Liam Joke?
Big B: A joke that’s not funny.

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.
