Someone who knows you better than yourself. Someone who you usually get into trouble with. Someone who has your back no matter what. Someone who can tell your secrets and everything to. Someone who loves you even with all your flaws. Someone who won't change who you are. Sometimes your partner in crime can also be someone who you're in relationship with, or a person you have feelings for, or just a friend.

A smaller version of group work, where one partner does all the work while the other partner does jack**** and still gets credit.
Partner work usually ensues in the ending of friendships.

Sarah... Does partner marking work?

Amy... Partner mark him! Wipe your fanny juice on his clothes, and any women who speaks to him will know his in a relationship. Partner marking works everytime
