My 2 cents on the discord name. I barely use discord so someone like welp may correct me here. I'm about ~10 years older than this group, but work with students and have younger family members, so feel somewhat hip (but sometimes it's like they have a foreign language).
It seems likely to me that group chat was pre existing and not something created for the video. IE, the name "Ella pissed herself" doesn't have anything to do with the video, the video was just shared in that group chat.
For example, I have a group chat called "[my name] and the losers" because I created it and obv had to poke fun at my friends. If I'm sharing a meme or something, I'd put it in that GC, but I wouldn't create a new GC like "meme name," it would just show up in my "losers" chat. And remembering high school, we always had embarrassing moments called out in chats. Like if someone mispronounced a word (one friend famously ordered a reeses pieces milkshake as a reeses
milkshake) that slip up would be the new group chat title.
What if "Ella pissed herself" is just an inside joke from some time ago with a group of friends OR a family group chat that they shared the video in. Also super possible they created a new GC, but I think it's pretty likely it's an existing GC name.
Also, as a Californian, to me "pissed herself" means messed up, slipped up, or got incredibly scared like at a horror movie. This is kinda what makes me think it's an existing GC, because I don't feel like it fits super well with the video contents, and more seems like an inside joke from something prior.
