Etymology: "Airheads" is the plural of "airhead," a compound of "air" and "head," and the insult comes from an image of a skull full of nothing but air where a brain should be. The "head" element is the old sense of the top or leading part of something, the same sense found in "beachhead" and "bridgehead." Military use of "airhead" for a seized patch of hostile ground, an airbase secured by analogy with those older terms, is a separate and earlier sense of the same compound. The personal insult grew from the same logic as "empty-headed," which already described a mind with nothing in it. Filling the head with air instead of thought turned a vacant mind into a literal, physical absence, which gave the term its bite. Its use for someone who is silly, frivolous or thoughtless follows directly from that image.
