One of the difficulties in the creation and upkeep of a dictionary is the issue of how to treat nonstandard language. English is constantly being refreshed with new slang words, some of which quickly wither and disappear, while others assimilate into the language and become standardized (our 1916 Collegiate listed awful, jinx, and measly as slang). Should the lexicographer enter every new slang term that comes along the dictionary would quickly become overloaded with words which have little current applicability; if too long passes before entering some of these words the dictionary is obsolete before it is published.
The compromise is to enter words after they have demonstrated a certain breadth and consistency of use, typically in printed form. A fine example of the kind of word that merits inclusion is asshat (“a stupid, annoying, or detestable person”), a word recently added to our dictionary. It occupies the space between assez and asshead.
It’s traveled pretty far into the language in just a short amount of time.
Asshat is a new addition to the English language. Recent research has found evidence of use from the late 1990s, in Usenet groups. (Note: the first citation below may be a pun on the misspelling of musical group Hatebreed)
