Who was the first person to use this phrase on EM? I'm interested in its origins, when it became popular, and as to how it's managed to hang around for so long
It existed when I joined in 2009 and I'd say it belongs to EM. Even if it doesn't, it's not widespread. MafiaScum, Something Awful, Vendetta Strada, the Spies series, and other communities don't use it.
