What does LLJK stand for and why?

I dont know what it means, but last night Cogworks had stated that Gibbed does not want the servers named after him anymore, even though he still hosts them.

I don't even understand what you're trying to say.

Rick ("Gibbed") hosts the servers. He does not want the servers to be named "Gibbed" after him any more, so they aren't.
