a prank
A prank is a girl who fakes being a slut but is actually a prude and acts like she's trying to make you lose your mind.
You asked her out and she said yes, but then she made you wait for 3 hours for a burger.
She sent you a shirt that said 'I love you' and it was covered in glitter and glitter is the worst.
She stood in front of the entire school and said she was your girlfriend, but she didn't even know your name.
