A collection of sauce produced from ones buttocks I’m the middle of the night. It can be used for anything related to use of a liquid such as poison or cooking. The typical storage of Butt Sauce is in a glass jar where your baby nephew can definitely reach and drink out of it. It’s also a racial slur in Scandinavia.
