Gadsden Purchase
A stupid, dirty way to have sex named after the Gadsden Purchase. You go to Mexico, pay a hooker, and then stuff your cash in her butt like you’re trying to win a bet.
'I did the Gadsden Purchase and won the bet.'
'You do the Gadsden Purchase and you’re a legend.'
'I had to do the Gadsden Purchase because I was out of cash.'
