Nam Vets
The Phrase "Nam Vets" is related to Vietnam Veterans and how after the war in Vietnam, most of the veterans of the war had Post Traumatic Stress Disorder, causing them to lose sanity and act like idiots around people.
We're going to have to go to the fair in a minute so stop acting like Nam Vets would.
