HoYay:

* Cable and Deadpool, who star in their own eponymous comic book series, are best friends/partners in crime/enemies/Heterosexual Life Partners with a healthy dose of Ho Yay. In one issue, Black Mamba uses her powers to distract Deadpool by making him dream of his greatest desire—which is rubbing sunscreen on Cable's back on a sunny beach.

o To the evil, evil man's defence, Black Mamba's second mind attack made Deadpool, Cable, Luke Cage, Power Fist and Weasel all fantasize about sunscreen related scenarios, with each other, presumably. There were lots of embarrassment.

o And directly after that he drops his pants to prove that the fantasy is bogus and he's "all man" by having sex with the B.A.D. Girls— revealing that he is still wearing the yellow panties he wore with the Marvel Girl costumed he'd donned earlier. You know, when he planned for Cable to be so distracted checking out his legs— and don't think he didn't see Iceman sneaking a peek too— that he wouldn't know what hit him when Deadpool struck? Yeah.
o Even other characters comment on the Ho Yay in Cable and Deadpool's sparring matches.
Deadpool: —Good sparring.
Cable: Was missing something...
Deadpool: Massage oil? ... did I say that out loud?
Cable: [Elbows Deadpool in the head.] That's what was missing...
Deadpool: Ben-Gay... stat!
Irene: If you boys are quite through eroticizing...?
o Well to be fair, Cable did that with all his training partners. [1]◊
o Then of course are Deadpool's comments about Cable's "naughty bits" and how Cable "could make that techno-organic mesh rise to the occasion when necessary."
o From Cable & Deadpool Issue 10:
The Cat: This is the component you were missing.
Deadpool: But I took everything you had in Japan—
The Cat: Only what I allowed you to take.
Deadpool: You are so totally the coolest...
The Cat: But how do you plan to get it to Cable in time?
Deadpool: We got this whole don't ask, don't tell thing goin'... not that there's anything wrong with that. Bodyslide by two...
The Cat: Don't ask, don't tell—? ...Oh. Oh.
o Deadpool and Weasel have a little bit of Ho Yay as well. Such as when Deadpool asserts that Weasel is "the perfect candidate for a nice, tight thong" when trying to convince him to take up the name Pool Boy and become Deadpool's official sidekick. The mention of Don't Ask, Don't Tell immediately after this comment does not help.
o And Deadpool is in the habit of fanboying The Cat when they meet.
o In an early issue of Deadpool's original solo series, Flatman appears to be hitting on Weasel a couple times. He offers Weasel a massage to make him feel better and calls him "sailor", which he tells Big Bertha is a term of endearment when she questions it.
o Flatman has since outed himself as gay. This was probably just foreshadowing.
o And then there's Bob of HYDRA, who's gone from hostage to unsure minion to adoring fanboy in the span of just a few issues. Seriously, what is it about Deadpool?
+ There's also the point that Bob has never, even early on, questioned or objected to being called Deadpool's pet.
