The condition in which you end up with someone in their room (usually during a party where alcohol is involved) and some form of sex is expected to occur. Before you end up in the room loop, you think it's a good idea to have sex with this person, but when you get there you realize how wrong you were. In this no-win situation one of three things happens:

1. You make up a lame excuse about your drunk friend and leave ASAP
2. You start to have sex, change your mind, and leave. Usually results in you earning a reputation as a blue baller
3. You have sex with them because you don't want to piss anybody off and feel like shit about yourself the morning after

You usually have about five seconds to make up an excuse to get out of the situation before it becomes socially awkward to do so later.

Even if you break out of the loop in the first few seconds, you will usually be asked to leave the party.

A pick me is a woman that is willing to do anything for male approval. She will embarrass or throw other women under the bus to achieve this goal. The unfortunate thing about a pick me is usually the men they are trying to seek approval from are of poor quality and treat women badly, leaving little real benefit for the pick me.
