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"
