The French Exchange
A situation where 2 people simultaneously perform the cupcake movement on each other after farting at the same time. The exact opposite of barter, due to it being 'a double coincidence of do not wants'
"I trust last night went well, Sir?"
"Bally terrible unfortunately Jeeves, i was planning to cupcake Aunt Agatha and at the very moment I gave it to her she turned and gave me one right back!"
"Ah, 'The French Exchange' Sir, a rare and exotic beast"
"Quite, Jeeves, quite- i've half a mind to leave her my Richmond Regards"
"Very good Sir"
