A Real Mary
A Real Mary is a girl who acts like she’s into you, but she’s just trying to get you to like her more so she can laugh at you later.
She said, 'I like you, but I’m going out with Trevor tonight.' Then she went to the movies with Trevor and texted me 10 minutes later.
She told me, 'You’re my favorite guy,' then sat next to her crush in the cafeteria.
She asked me out, said yes, then dumped me for the quarterback.
