A Real Mary
A Real Mary is a girl who gives boys the illusion of a chance, just so she can feel superior when she turns them down.
She asked me to prom, said yes, then went with her crush to the prom.
She said, 'I like you, but I’m with Chris now.' Then I saw her and Chris eating pizza in the park.
She told me, 'You’re the best,' then kissed her friend in front of me.
