Portmanteau

A portmanteau (pronounced \pȯrt-ˈman-(ˌ)tō\) is a new word formed by joining two others and combining their meanings; "smog" is a blend of "smoke" and "fog"; "motel" is a portmanteau word made by combining "motor" and "hotel".

The word itself is an obsolete term for a kind of suitcase that opens into two hinged compartments. It was first used to describe blends of words by Lewis Carroll in Through the Looking-Glass, and What Alice Found There, when Humpty Dumpty explains to Alice the word "slithy" from the poem Jabberwocky:

""Well, slithy means lithe and slimy ... You see it's like a portmanteau -- there are two meanings packed up into one word.""

Before first-letter acronyms were standard, this was thought to be just fantastic by up-and-coming political movements in the '30s, which is why we have the words StuKa, NaZi, GeStaPo, StaSi, GULag, ComIntern and SovNarKom, which is why nobody uses them anymore (in Russia, some of these portmanteau acronyms survive). Consequently, fictional totalitarian governments often use them to play on these connotations. In countries that don't use alphabets, like Japan, this is still the standard, which is why Portmanteau Series Nickname is full of anime show examples.

Incidentally, the original French word "portemanteau" is a portmanteau. "Porte" means carries and "manteau" means coat, so a portemanteau is something that carries your coat. In modern French the word means coat hanger instead of a type of suitcase.

Anime & Manga

 * Yaoi = yanma nashi ochi nashi imi nashi . An alternate (joking) portmanteau for yaoi is "Yamete, oshiri itai!"
 * ROD the TV: Joker's codename is a portmanteau of his real name (Joe Carpenter). (Well, or maybe Joe Carpenter is a pseudonym derived from the codename...but either way, portmanteau.)
 * In the Pokémon episode "Short and to the Punch", Clayton the martial artist insists on giving portmanteau nicknames to everyone and coining abbreviations for common phrases. For example, Ash and Buizel are referred to as Ashbui. This trait was carried over largely unchanged from the Japanese version.
 * Digimon = Digital + Monsters.

Card Games

 * Magic: The Gathering
 * The fans do these with combos, like Land Tax (If your opponent gets more lands than you, you can search your library for three lands and put them in play.) + Armageddon (Destroy all lands.) = Taxageddon (for massive mana advantage and card advantage). Yawgmoth's Bargain (pay X life to draw X cards) + Heroes' Reunion (gain 7 life) = Heroes' Bargain (or two and a third Ancestral Recalls, which, to be fair, requires you run a three-color deck).
 * Occasionally used for actual cards, such as "Blightning" and "Deadapult".

Films -- Live-Action

Pro Wrestling

 * Edge and Christian were infamous for doing this sort of thing. The best example was ramipercussions, a combination of ramifications and repercussions.
