Oh man, I'm going to get made fun of for this, but... The Barbie movies. Especially The 12 Dancing Princresses. My sister and I watched it so many times as kids that we could quote the entire thing (we often did so while watching it lmao). Honestly just off the top of my head now I probably could quote a good 80-90 percent of it. We must have watched it more than a hundred times, not even exaggerating.

My guess is that OP is going to be in a circus performance (which explains the large tent with air conditioning). As to the reason they don't want to poop, it might be because:

• their costume(s) are difficult to remove
• there is something about the bathroom that they find creepy/unsettling
• they have an STD or other infection in that area of their body and don't want to risk having anyone find out unexpectedly, or don't want to risk spreading it to others via the toilet seat (gonna be real idk if thats even a thing but it feels like it could be)
• they hold some kind of superstition about pooping during the initial travel period, or about entering the bathroom, or something that is in the bathroom
• they have to get to the bathroom by passing an area and/or person that they dislike and/or feel uncomfortable around
• they take notoriously large shits and don't want to clog the toilet
• they just have really bad poop anxiety

Anyway, best of luck to you OP. Hope whatever you're doing works out and that you stay as safe as you can. Update us when you come back!

If you mean the "I need to go 3 days pooping as much as possible" post, it's a reference to this post from a couple days ago

HELL YEAH, FUCK NESTLE

Oh god not silverfish, I had a few in my bathroom a while back and I spent like three weeks spraying all the nooks and crannies with lavender-scented spray every day to make sure no more of them came back. I like bugs but those are some creepy little fuckers. And they eat your books!
