American Soup

Ice cream or frozen custard that has been melted into a liquid, soup-like consistency

The ice cream was sitting out too long, and it turned into American Soup.

South American Soup Bowl

The act of taking bowling hot soup (normally chicken noodle, egg drop, cheese and broccoli, etc.) and pouring it into a females vagina, then eating it with a spoon. The sound produced by the female after having this performed is similar to the Guanaco, which is an animal native to south america, hence the name South American Soup Bowl.

Ethan: "I heard you gave Sally a South American Soup Bowl last night."
Carson: "Yeah, she told me that she will put my penis in a zippeh as revenge."
