Speaking of imaginary boyfriends, in one episode Grandpa refers to Yami as "Yugi's invisible boyfriend."
Let's face it - any scene featuring Marik and Bakura will result in large amounts of this trope. In the recap episode, their teaming up was described with Florence claiming they should be partners. Marik responded “You mean like partners in crime?” and Florence replied somewhat sarcastically. In episode 40, Florence tells Marik it's a good thing he's pretty, because otherwise he would have suffocated him. In the "Leather Pants" video, Marik says that both him and Florence are quite hot and sexy and there is a shot of them standing very close (with sparkles) to the line “And we're really Just Friends!” Right before they die at the hands of Melvin, they sing "Stand By Me" in a duet, and in a deleted scene, got a Dying Confession of Hate so foe yay-riffic it's currently the page quote for Foe Yay/Anime. Incredibly? Their Ho Yay only gets more blatant in Marik Plays Bloodlines:
Prostitute: Okay, honey. Let's see what you've got.
In "Marik Plays Bloodlines", Marik and Bakura have this conversation:
Marik:Most people already know that when you open a dictionary and look up the word "sexy" that is has a picture of me. More specifically a picture of my bottom because that's where I store my sexiness!
Bakura:Marik, can I borrow your dictionary?
Apparently, Bakura was doing a crossword puzzle. A very "hard" crossword puzzle. Marik remains oblivious, as per usual.
And now in Marik Plays Bloodlines episode 6, Marik has admitted that he's gay and keeps a whole folder filled with Thiefshipping pictures on his computer. Amazingly, he still denies that any of this is true, at first claiming that Bakura couldn't hear him, and then blaming the ghost in the game. It's becoming increasingly obvious that the only thing stopping Marik and Florence from being full-on Yaoi Guys is Marik's inexplicable insistence that he is not gay.
Though its status as canon is debateable, LittleKuriboh has written a fanfic, set in the Abridged Universe where Marik and Bakura actually do get together. Though Marik still isn't gay. Apparently.
Marik:: I mean, you know that I'm only gay for you! I'm very comfortable with my gayness where you're concerned. But as far as anyone else goes, totally hetero!
The episode "What would Yugi do?" has so much Yami/Yugi Ho Yay. From Yami's side at least.
"You should buy the whipped cream for later ... you know ... for snacks."
"Apparently we're supposed to...do you."
Melvin:: I always knew you wanted me to be inside you, Bakura!
Yugi: Aw, that's cute! Duke and Tristan got their own little hole!
Duke: We've gotta get outa here, dude! I kinda have this disease where if I don't have half-naked girls applied to my body at regular intervals... I die.
Tristan: Want me to take my top off?
Duke: I said half-naked girls!
Tristan: How do you know it won't work if you don't try it?
In "The Other Abridged Movie," Kaiba has security cameras set up all through out Japan and spends a lot of time spying on Yugi, including watching Yugi taking a shower everyday so that he can always be "one step ahead of him." There is also Joey's whole "surprise buttsecks" thing which he does to a random henchman and Yugi. Some example dialogue:
In "Marik's Evil Council 4", Melvin declares that now that Yugi is dead, Bakura will be his boyfriend and they will "go out ten times". Shortly afterwards, Zorc tells Bakura that Zorc And Pals is getting a second season, and Dan Green tells him that "Florence" has just been voted the manliest name ever. Bakura says that this is the happiest day of his life. Too bad that was All Just a Dream.
In the movie, Pegasus flirts a lot with Kaiba. "How about I smother your naked body in cream and lick it off?" indeed.
Of course, it could be Pegasus trying to piss off Kaiba for the lulz, since in the series he's established as Camp Straight.
A lot in Bonds Beyond Time Abridged. Firstly there's Yusei telling Jack Top Gun isn't gay because it's totally straight for two guys to call each other cute nicknames, play half-naked volleyball, and ride their phallic vehicles at extremely high speeds. Jack then says it's time to ride their motorcycles and play some half-naked volleyball.
Pegasus: I'm not even going to comment on that one.
Kaiba/Yugi in Kaiba Finally Snaps, a parody of Mel Gibson's infamous rant at his girlfriend. Apart from Kaiba's card game related double entendres and his obvious obsession with Yugi, there's suspiciously heavy breathing. Because Kaiba is angry at Yugi. Right.
When Kaiba enters the classroom in the second episode of season 0, Yugi says, "He's dreamy!"
There's oodles of this between Kaiba and Pegasus in the Conclusion to Kaiba's Real Father, but this takes the cake:
