You're having a movie night, but he keeps SPOILING twists before they happen.

just LET THE MOVIE TELL THE REST OF US!

Inspired by how he seems to REALLY enjoy telling you what's going on in the game. I can use context clues bro, i'm not THICK.

But yeah, this is something he'd do. not out of spite or to be annoying, but he just gets to excited when he realises it that he blurts it out without thinking maybe some other people want the twist to BE A TWIST.
