Hair trap
A hair trap is when you think a girl is a goddess because of her hair, but then she shows up and looks like she just got run over by a truck.
He was in love with her hair, then she turned around and he got a nosebleed.
She had hair like a celebrity, but her face looked like it was drawn by a toddler with a crayon and a grudge.
He asked her out, she said yes, then he saw her face and ran.
