Natoid

An individual in the internet or someone you know personally that is a fervent supporter/enthusiast about the North Atlantic Treaty Organization (NATO). They are most commonly found in military forums and are generally condescending towards fellow military enthusiasts that prefer military topics that are not NATO related.

"Dude, this Bert guy keeps telling us how NATO weapons are much better than Chinese or Russian ones."

"Don't mind the guy, he's clearly a Natoid."
