ELI5: Explain Like I'm 5

Kibitzer

Okay, so you know when you're playing a game or watching a game, and there's someone who's not playing or not on the team, but they're hanging around and talking about what's happening in the game? That person is called a kibitzer.

It's kind of like when you and your friends are playing a board game and your little brother or sister comes in and starts saying things like "Oh, you should move your piece there instead!" even though they're not really playing. That's what a kibitzer does. They don't actually play the game, but they like to watch and give their opinions and advice.

And just like with your little brother or sister, sometimes the kibitzer can be helpful and give good advice, but other times they're just being annoying and distracting.

So that's what a kibitzer is, someone who likes to watch a game or activity and give their opinions and advice, even if they're not actually playing.
