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"

Similar to a monroe transfer, however, both partners have the same tube up their asses and they both defecate. In the case of diarrhea, some poo may be "exchanged" into each others rectum. Most enjoyable.
Paul and Patty decided to try a Monroe transfer but the tacos they ate the night turned it into a Monroe exchange.

A variation of the "Eiffel Tower". This move requires two males and one female. The males shall be dressed in business suits. Unlike the Eiffel tower, instead of high fiving, you will shake hands and look each other in the eyes in agreement. Upon completion of the Stock Exchange the males will check their watches as if late for a meeting and leave while the female is left to clean up the "paperwork".
Mr. Steve and Mr. Bob walk into a room. Ms. Jenny was bent over a chair. Mr. Steve and Mr. Bob unzip their slacks and insert their penis' into the respective holes on Ms. Jenny which were agreed upon previously. When both gentlemen are inside, they shake hands until they have completed the transaction of dumping semen into Ms. Jenny. Stock Exchange complete!
