Here is a gigantic list with over 500 pairings for Duel Monsters alone, and here is a link that has a shipping list for each of the spinoffs. There are even _ Shipping for OT3s, like Entourageshipping (Diamond/Pearl/Platinum).

Franticshipping (Ruby/Sapphire), Oldrivalshipping (Green/Blue), and Specialshipping (Red/Yellow) come to mind. Similar to the fandom for the anime, the Pokémon Adventures fandom uses the '_ Shipping' naming scheme.

Similar versions were used for some other ships, such as JAJL for James/Jessie, and they lasted a while, but they eventually failed due to being associated with the more 'immature' parts of the fandom and the rotating cast making the names confusing the aformentioned AAML could be for either Ash and Misty or Ash and May.

At the beginning of the Pokémon fandom, the Ash/Misty relationship was referred to as 'AAML' (acronym for 'Ash and Misty Love'), a blend of Idiosyncratic and Portmanteau Couple Name.

Other common names include Orangeshipping (Tracy/Misty), Contestshipping (Drew/May), Ikarishipping (Paul/Dawn), Egoshipping (Misty/Gary), and Wishfulshipping (Iris/Cilan).

The various shipnames involves the protagonist Ash Ketchum are Pokeshipping (Ash/Misty), Advanceshipping (Ash/May), Pearlshipping (Ash/Dawn), Negaishipping (Ash/Iris), Amourshipping (Ash/Serena), Aureliashipping (Ash/Lillie), Blueangelshipping (Ash/Lana), Journeyshipping (Ash/Goh), Bloomboltshipping (Ash/Chloe), Palletshipping (Gary/Ash), and Imaginationshipping (Ash/Bianca).

'RocketShipping', which pairs Jessie and James of Team Rocket.

It makes sense, as the first name of this type, Rocketshipping, was conceived as a pun on the term rocket ship. Given their records showing this form of ship naming in use as early as 1997 or 1998, even if they weren't the first to use it, they're certainly one of the first.

Pokémon: The Series: The Pokémon fandom actually claims to have invented the '_ Shipping' (with the blank space filled by a word or phrase that applies to both characters, or combines different aspects of them) trend.
