I had a friend that would play stuff like that over his mic. Load up a juicy YouTube video with lots of drama and let everyone in the lobby think it was real. Especially if he went AFK.
It was pretty funny tbh. He wouldn't do it all the time, just when a lobby was kinda dead. We were young immature teenagers during the beginnings of prank culture.
That reminded me of the Unemployed Wine Guy, a somelier who started doing kind of parody reviews during the pandemic. The story advanced through each video. It was pretty fun!
That's what I thought of too. I heard he kept making videos, and eventually she's back, so I guess she changed her mind and they stayed married.
Edit: I just watched it and this is actually a different one. The one I saw was with a younger couple and he doesn't say anything about her leaving. He just does his review and she's in the background throwing shit around, and moving boxes.
