Octopus Babies was a joke team that partook purely in the competitive battling sections and won a War. Kind of recent, actually. That's considered a fiasco.

A joke team is considered a team that has zero substance or is just a War-related thread that is completely random. There was a team about animated gifs in the same War. Also a joke team. It's about as bad as titling your thread [WAR] My Team and for the opening post saying this is a War team, join please. I'd be like, why? Your team is about nothing. A joke team is pretty much defined as a team that has no semblance of what it's about and equates to this is a team, join.
