A slang, derrogatory term for the Linux operating system. Similar to the term Windoze.
Fred: I just spent all day compiling my kernel and setting up.
John: I spent all day playing games. That'll teach you for using Linsux. Windoze may suck also, but at least I don't spend most of my time messing around with it, I just use it.
A reference to the quite clearly awesome Anti-Linux website, Linsux.org
Dude, have you checked out Linsux today? They ripped Boycott Novell a new one!
