A sexual act where one partner lies down face-up on the ground while the other squats down over them like Bigfoot at a stream and poops in their mouth. The lying-down partner holds the poop in their mouth and then stands up and makes out with the other person, going all "Lady and the Tramp" on the poop.

Note: The partners involved in the Minnesota Bigfoot can be of any configuration: male-female, male-male, female-female
Yesterday I met this fine chick at Church and when we went home together I gave her the Minnesota Bigfoot.
