Person Above: Fill yer (under)pants!
 

This is how it works...

Starting with this as the first post, the next person posts what I have to fill my underwear with.
Depending on the persons limits this could be shaving foam, piss, feathers, custard, gunge, soup, yoghurt, melted ice cream etc.

Then the next post applies to the previous respondent. PM people if you want to make sure they’ve noticed.

Perhaps spice it up with variants like ‘stay in this for an amount of time’ or request a write up/Kik pic (if they’re ok with that).

Have fun, get creative.
