my bum your bum 

This is a couples' game; you blindfold one participant, then the other person sticks a digit in their bum and a digit in their partner's bum, one digit from each hand.
Then, wave the differing fingers under the blindfolded participant's nose, to see if they can guess which finger is which, whilst repeating with each finger swap... "My bum.... your bum?!"

Let's play my bum your bum...

I recognise that shit smell anywhere.... that's not my bum , that's YOUR BUM !

Makes my bum go in

My boss has just seen me on only fans and it’s totally makes my bum go in
