In computer and video gaming, a clan or a guild is a group of players that play online games together.
Based on this, a Minecraft clan would be a group of people (likely united under a name and acronym) that play together in a specific server or across a multitude of servers. They may have specific jobs within their clan (builder, miner, lumberjack and so on). They might even have a website.
A main reason to form a clan is to attract like-minded players and to form new friendships. It may also be the sole purpose of the clan to do battle with other clans in a PvP environment. They could decide to play a gang role in a server as they steal and kill their way to glory.

The possibilities are endless, I suppose.
