Avril Lavigne.

You were at a party with Avril; she had you sitting on her lap, kissing your neck and leaving marks. Until you got thirsty and went to get a soda, but you ran into a former college friend and stayed talking to her. When Avril saw you were taking a long time, she got up to see where you were. And when she saw you with that girl, Avril gave you a furious and intense look, letting you know she didn't like you being with that "friend."
