For the rest of us, what does “echan” mean? Searching online for “irc echan” wasn’t much good.

edit: some wider-range searching suggests it might be Spanish for “kicked”.

"Echan" = "empty channel" - IRC slang for joining a channel, seeing no recent activity, and immediately leaving.

It's considered bad etiquette because IRC channels are often quiet but still active - you're supposed to stick around and just ask your question directly rather than bailing when you don't see instant chatter.
