Fun:Malamanteau

A Malamanteau is a neologism for a portmanteau created by incorrectly combining a malapropism with a neologism. It is itself is a portmanteau of malapropism and portmanteau.

Really?
No, not really. It was made up by xkcd author Randall Munroe in a May 2010 xkcd comic strip. It subsequently lead to thousands of people try to look it up on Wikipedia - only to find that there was no article and the word didn't exist. This lead to a literal metric fuckton of butthurt as people thought "hey, let's make it an article!!! L0L!!!!11!" while more boring regular Wikipedia editors tried to repeatedly delete it. They even got to the point of trying to claim that "bbcnewsamerica.com" was a real news site, so was reliable.

Undoubtedly, it was totally hilarious for all involved. It was probably less of a joke on words that Wikipedia uses a lot in articles, and more a joke on xkcd fanboys who like harassing Wikipedia.
