An inside joke is a joke that only a few people understand because it was based off an incident or something another person said.

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"

What Urban Dictionary claims to do, but really if you just search a name you find a bunch of praise for friends and partners.
Urban Dictionary: "Don't name your friends. We'll be rejecting inside jokes and names of non-celebrities."
Me: "But didn't I just see a bunch of non celebrity naming?"
