A word mainly used a woman who is a total
ditz, and get by
soley due to the fact that they're hot.
Airheads are usually full of themself, obsesed with clothing & makeup, and are just plain dumb. They kill the words "like" and "totally", because those are like, totally every other word they, like, use.
My ex girlfriend is such an
airhead, she bought $2000 worth of
cloths on her credit card because she didn't know you still had to pay for it later.
