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"
an ass hat is someone who still uses the term ass hat.
What I type in google to see if I have internet. Usually done if my wireless network takes a shit and I have to search something random to ensure I do not get a cached page.
Unplug the router, plug it back in, head to firefox and type in ass hat to make sure everything is back online.
