This is a game about a unisex Superman t-shirt, and the strange places it ends up.
Rules
Someone writes a paragraph about someone wearing the Superman t-shirt. As little or as much as you want, just try and mention how the person uses the t-shirt in their lives. Remember to put it in bold.
"Alice is wearing the Superman t-shirt. She's a Libra, and hangs out in nightclub toilets for undisclosed reasons. The t-shirt helps people identify her when she gives them instructions to meet her."
The person below them must explain how their someone got the t-shirt off the last person.
"Bob met Alice in a nightclub and traded his ecstacy pills for the t-shirt."
Then they write a paragraph, like the last person.
"Bob thinks he's a mystery novelist, but he's never actually written anything. The Superman t-shirt reminds him of his ex-wife, who was a serious comics nerd, so he wears it to remind him of her."
Repeat ad nauseum.
Tips
Try to yes and. Instead of introducing a whole new element, try riffing on the last person's post. Even better, go way back to another user and circle around.
This will start in a modern Earth, but it's totally okay if you want the t-shirt to go back in time or hop dimensions. In fact, it's encouraged.
Try not to destroy the t-shirt, or alter it to the point where it's no longer a t-shirt. Tears, stains, and mods should be fine.
To begin:
Brian won the t-shirt in a phone-in radio competition. He mainly uses it as a nightshirt as his apartment is extremely cold.
