Admit it, you do it. I mean, your mom does it. Your best friend does it. In fact, everyone does it—and it’s nothing to be ashamed about. What’s “it?” Well, it’s SSB, or your Secret Single Behavior. According to Urban Dictionary, the term originates from a Sex and the City episode in which Carrie and Charlotte describe the behavior people have when they are home alone and no one is around. For example: Charlotte examines every pore in a magnifying mirror, while Carrie stacks saltine crackers with jelly.
