Ho Yay in The Grim Adventures of Billy & Mandy.
- Lord Pain towards Grim in "House of Pain". He kisses his feet, pleads to be his slave and strips in front of him to show his Grim tattoos. He gets over him and becomes Mandy's servant instead and gets Mandy tattoos in a later episode.
- Irwin and Nergal Jr. were both rejected by Mandy. At the Valentine's Day dance, they decide to dance together without hesitation.
- Billy to Grim: "Now bend over and let me RIDE YOUR HUMPS!" He's also admitted love to Grim.
- In "The Incredible Shrinking Mandy", we get this... slightly disturbing line:
Billy: Listen Grim, I'd do anything... (suggestively) and I mean anything (grins and flutters eyebrows)...to cheer you up! - The ending to "Billy and the Bully" is rather Ho Yay-ish, having Sperg and Billy do such things as hugging tightly, riding a tandem bike, and skipping happily through a flowery meadow together.
- "Company Halt": After Hector Con Carne finishes explaining his giant rubber band attack plan, General Skarr exclaims, "I love you SOOO MUCH, Hector!" and hugs him (or rather Boscoe, to whom his brain is affixed) tightly. Hector responds with, "Yeah, I... love you too, Skarr." as Boscoe hugs Skarr back and makes affectionate noises. Ghastly backs away slowly in awkwardness.
- Dean Toadblatt makes out openly with Squidhat and the two are wed in the same episode. Toadblatt was under the effects of a love potion... but Squidhat wasn't.
- Mindy sometimes seems rather...obsessed with Mandy. It's shown that when they first met Mindy tried to befriend her before Mandy couldn't take her inane small-talk and blew her off. Since then Mindy has gone out of her way to try and impress Mandy or else show her up in various ways. Pretty much half of what she does seems to be geared toward getting Mandy's attention and she shows that she still really cares about what Mandy thinks of her.
- There's a couple of moments between Irwin and Billy as well:
- Irwin's crush on Mandy is actually probably because of this. One of the things Billy does in Mandy's body in "Get Outta My Head!" is flirt with Irwin, even calling him a "cutie". Keep in mind that this is Irwin's first appearance.
- Later, in "King Tooten Pooten", Billy offers to be Irwin's queen (even though Irwin's sentiment was directed at Mandy).
