My interpretation of asshat:
A hat for asses would be frivolous and of little use. I picture one of those cheeky (snort!) little hats that need an elastic band to keep on your head only its resting on someone's ass.
Above your ass is the rest of your body including and most importantly, your brain. If you are vapid, pointless and irritating, one might be suggesting that what sits above your ass is of little importance or use.
For the purposes of staying on topic....
Wouldn't coming up with some word that describes the people the OP is talking about be about the same as the term vanilla making such a word snide and petty? Its like willingly getting into a childish slap fest over who's dad is bigger.
