I despise that term.
I think it was coined (and is certainly promoted) by certain contesters who are full of themselves. These are the clowns who think that the WRTC is the radio contest equivalent to the Olympics. These are also, for the most part, the same turkeys who believe "anything goes", "if it's not specifically prohibited it's allowed", and "if you don't catch me it didn't happen." And don't get me started on the "open logs" nonsense.
These are some of the worst agitators -- they are the minority that gives ammunition to the contest haters.
I am not a "radiosport-er". I am a contester.
