Stuilly

Stuilly is the slash ship between Stuart Macher and Billy Loomis from the Scream fandom.

Canon
Stu and Billy were best friends, going to the same school - Woodsboro High School - and, as revealed by the end of the Scream (1996), the Ghostface.

We could already see the two boys getting along at the beginning of the movie. From what we saw then, they were spending a lot of time in school in four - Billy, Stu, Sidney (Billy's girlfriend) and Tatum (Stu's girlfriend). We could also see Stu Macher and Billy Loomis associating with only each other in their free time.

As we find out by the end of the film, there was a good reason for showing them being so often together. Billy and Stu were partners in crime, the Ghostface/Woodsboro Killer. Loomis, despite saying he didn't have a motive, he actually had it. That being his long-running hate towards Sidney's mother for 'ruining' his family, despite the fact he already killed her. Yet we never find out Macher's motive. However, when Sid calls the police and asks him what she should say about his motive, he chooses 'peer pressure'. It's possible that it wasn't so far from the truth and he became Billy's partner in crime, just to help him in accomplishing his plan.

While Macher and Loomis talk with Sidney alone, they mention that they were preparing for being Ghostface - watching horror movies and taking notes together. The two boys also had the whole, perfect plan in mind, which also means they already talked about the 'ending' a lot.

Moments

 * When Billy 'talks' with Randy Meeks in a video store, Stu holds Randy, so he wouldn't run away.
 * When Billy and Stu talk with Sidney after revealing that they're Ghostface, Macher presses his body against Loomis's back and - for a moment - rests his chin on Billy's shoulder.

Fanon
Stuilly is the most written ship on AO3 in the Scream (Movies) tag and the most written ship for both of the characters. It's also the only ship with fanarts in the fandom. It currently has over 300 works on AO3. The ship sailed because of Billy and Stu being partners in crime and because of the especially visible closeness between them, which made a lot of Scream fans think that they were in a relationship.

In Scream 4, there's a similar relationship between Jill Roberts and Charlie Walker, who were canonically a couple and - in a few points - openly imitating Billy and Stu's actions. It might be a proof that Stu and Billy were really a couple too, yet it still wasn't directly confirmed.
