When you get to know a girl and may be have a flirt, too and she suddenly turns colder and tries to unobtrusively place the words "my boyfriend" in the conversation she is boyfriending you to impact that you do not have a chance to score.
Usually this happens when you have done something that made her reconsider (in this case often there is no boyfriend) or she did not have a drink for more than half an hour and begins to have second thoughts about cheating on her (existing) boyfriend.
Boyfriending:
You: "Did I tell you that i travelled the world for the last couple of years?"
Her: "Aaah, that sounds interesting. My boyfriend went on a three weeks vacation last year too."
