Internet Relay Chat; It's how hackers talk when they don't want to be overheard. It's a pretty primitive chat program. Think of it like shipping channels in the ocean: you can't see them until a boat cuts through the water leaving a wake. If two boats meet in the middle of the ocean to swap a load of illegal drugs, you have to catch them in realtime. Otherwise there's no record of the meeting left behind.
