It's funny you mention this, I was just thinking this other day we may eventually be in a future where a group hangout party could look like this:
1. Goes to friends' place
2. Usual drinks, whatever gets you going activity
3. Each person writes a prompt
4. Chain them together
5. Watch the resulting movie together
I'm vaguely reminded of the excellent Jackbox game Tee Fury, in which players submit slogans for T shirts and "art" separately. Players then get to choose from a few options for slogans and designs to make T shirts which are voted on by the group.
I have fond memories of laughing until I was in tears when playing with a group of friends over drinks during the lockdowns in 2020. Something about the process just naturally results in hilarity (especially if you're in a group where you can be offensive).
It's like exquisite corpse for t-shirts. Or, in your case, shorts.
Whenever one of my friend groups is gathered we always make it a point to do an exquisite corpse story on a piece of paper while we’re inebriated in some way xD Video version will be wild
