This will be an idea for a one shot

Jack and Mark are finally living together in LA and this is their first Halloween together and they spend it drinking hot chocolate, watching horror movies, scaring each other, pranking each other, and other things...when Halloween night finally comes they hand out candy to the kids that come up and knock on their door. When that's over they get in their costumes and head to a party that Bob and Wade were hosting, it was like a giant Youtuber Halloween Bash! Which is what the flier said, and Mark went as a sexy scuba diver and Jack went as a merman (OH MY GOD NEW STORY IDEA!) and nobody knew about septiplier yet and Jack ended up getting seriously hammered and he went on stage with mark to sing some karaoke, and at the end of the song Jack kisses Mark and the crowd goes silent...before they FUCKING CLAP AND CHEER THEIR ASSES OFF BECAUSE SEPTIPLIER! And who doesn't ship septiplier? Even a little bit. Mark ends up taking the drunk Irish baby home only to find that he was a *ahem* interesting type of drunk and one thing led to another and the trick or treat candy was gone. Hah nope just kidding, they had sex.

That's all I got .-.
