Get the Super sister mug.
When you and your two friends who are good looking enjoy a hand full amount of partying with ugly people.While you are partying, you are also soul sisters, and that makes the partying so much better. You form what is called a super party soul sister trip dick, where one of you walks into the party in the middle, with a sister on each side.
"Hey guys, I hear that the super party soul sisters are coming out tonight! It's gonna be a great party!"
