If your head is filled with air instead of brains, you probably can't think very well.
2) I wouldn't ask Alaine for the answer -- she's an airhead!
1. Ignorant, stupid, dumb, idiotic person who is incoherent to almost everything and is absolutely clueless.It can be anyone.
2. Most men who think and stereotype an airhead as the majority of attractive women out there are the airheads, because what dip shit would randomly look at a female and say 'Oh, she's hot but she's an airhead', and pull this out of a hat. Then accuse some pretty college chick of being an idiot when they could have had a long life with the girl! When they can be getting somewhere and a relationship with a smart and pretty woman! That's what I call an airhead. What the hell is that?
Jamie's such an air head, the grammar she uses is so awful it's so incoherent and the way she spells immature- "emuchur." What is that? She's 21!
