> It occupies the space between assez and asshead.

The fact that asshead, a word I can honestly say I've never heard used in any English dialect, merited inclusion before asshat, a word I've heard a dozen times this last week, boggles my mind.

[anamexis]

Well, as noted in the article, asshead has a few hundred years on asshat...

Words also lose notability and are removed from the dictionary all the time. Literally the inverse argument for adding "asshat".

[anamexis]

Words are usually just removed from print editions to manage space. Otherwise they are just marked as obsolete or archaic.

[deaddodo]

Sure. Asshead is marked as neither.
