I open thread Starshipping 
The ship is composed by Judai Yuki (Yu-Gi-Oh!GX) and Yusei Fudo (Yu-Gi-Oh! 5D's); the ship is called 'ship crack' because it is of different series.
The origin of the name is not yet clear, but it is said to be called "Starshipping", because Judai traveled into space on a satellite; and Yusei is the star of Satellite, idk 
The ship begins to popularize from the encounter that takes place in the special film "Bond beyonds time", where the protagonists are Yugi Muto, Judai Yuki and Yusei Fudo. The chemistry becomes instantaneous in both, since Yusei saves Judai from a Stardust Dragon.
One of the most 'immortalized' scenes, is when the two of them start talking on the roof of the 'Plaza San Marcos, Venice', in which, Judai at first doubts the story of Yusei, but then ends convinced.
The next moment, the spirits of Judai [Yubel and Daitokuji], affirm that Yusei has spiritual powers, because Judai winks at him when Yusei shows him his dragon mark, in some way, he sees a kind of flirting.

The second most iconic scene of the whole movie, in which Judai and Yusei travel to Yugi's time, on Yusei's D-Wheel. The image can even feel ...
The third most important scene, in which, Judai borrows Junk Garda (Yusei's Monster), and uses it as a material for fusion as shown in the video.
Likewise, they work well as a team when they have to save their monsters from a Paradox attack, in which, Judai uses the defacement card, and Yusei uses a Junk Gardna effect.
The last iconic and most beautiful scene in the movie is when they say goodbye to each other on the roof, they hold hands and the way Yusei grabs Judai's hand, is ... is very tender.
Conclusion: this ship is very beautiful due to the fact that both Judai and Yusei have their differents in their personalities, one is fun and active, while the other is calm and peaceful; so they both, would work perfectly as a couple / boyfriends.
Bonus track +
Bonus track +
Bonus track # 1: Yusei in the WRGP makes an invocation for fusion inspired by Judai Yuki.
Bonus track # 2: A "Duel Vocal" was released with both on the cover.
Bonus track # 3: In one of the lines of Duel Links, when Judai loses against Yusei, he tells him: "That he has not lost his smile in the whole duel"
I add as a curious fact, that the figure of Yusei goes on sale on the birthday of Judai Yuki (August 31)
