When the Oxford English Dictionary announced the release of this year's edition of its authoritative compilation of the language, Carl Franzen at AOL News noticed that there was a conspicuously large number of new, slangy words being added to the vernacular by the venerable dictionary's editors. Words that would commonly be found in, say, Aaron Peckham's widely-read Urban Dictionary, an online collection of 21st century words and terms like "beer me" and "Cubicle Coma." In a side-to-side comparison, Franzen finds that the two dictionaries aren't as different as they appear on first glance. Here are a few choice comparisons from his list:

Bromance
Oxford: n. informal a close but nonsexual relationship between two men. – ORIGIN early 21st cent.: blend of brother and romance.
Urban: Describes the complicated love and affection shared by two straight males.
Hater
Oxford: n. a person who greatly dislikes a specified person or thing: a man hater | he's not a hater of modern music. informal a negative or critical person: she found it difficult to cope with the haters.
Urban: A person that simply cannot be happy for another person's success. So rather than be happy they make a point of exposing a flaw in that person. Hating, the result of being a hater, is not exactly jealousy. The hater doesnt really want to be the person he or she hates, rather the hater wants to knock somelse [sic] down a notch.

Carbon Credit

Oxford: n. a permit that allows a country or organization to produce a certain amount of carbon emissions and that can be traded if the full allowance is not used.

Urban:
A SCHEME by the rich to continue their polluting guilt free, while the poor will have to make sacrifices for the environment so the rich can continue to pollute.
