Idiotic, stupid. To act like a moron.
From the popular insult "to have your head up your ass". This imagry leads to ones ass being placed on the head like a hat, hence "asshat".

a once great insult that hit the internet late 2003. While never reaching an annoying state of over use, it has now been put out to pasture due to it's use on the FOX series "the OC"
