ObsessiveMathsFreak writes "Today's xkcd comic introduced an unusual word — malamanteau — by giving its supposed definition on Wikipedia. The only trouble is that the word (as well as its supposed wiki page) did not in fact exist. Naturally, much ado ensued at the supposed wiki page, which was swiftly created in response to the comic. This article has more on how the comic and the confusion it caused have put the Net in a tizzy. It turns out that a malamanteau is a portmanteau of portmanteau and malapropism, but also a malapropism of portmanteau. All this puts Wikipedia in the confusing position of not allowing a page for an undefined word whose meaning is defined via the Wikipedia page for that word — and now I have to lie down for a moment."
