Walk of Shame.

Let's say, for the purposes of this post, you are a guy. You have just hooked up with a decent looking girl...you got some action, she got some cuddling, all parties are happy. The next morning, your friends come to your bedroom door, trying to awaken you for some new shenanigans. She wants to get changed, and they're not budging from the door. Trying to save some semblance of class, she decides to change in the shadow of your closet, far from the prying eyes of your friends.

After reading too many issues of Cosmopolitan, she thinks it'd be cute to get changed seductively, intending to kick your boxers she was wearing onto your bed after removing them. While attempting to perform this maneuver, she gets the boxers stuck around her legs, trips, and falls into your closet, wearing simply a bra and underwear. 

For the sake of my pride, let's just say this is totally a hypothetical story. However, I would really, really empathize with any girl it did happen to. Totally.
