Hair Booger
A booger in your hair, usually from a kid who thinks hair product is a snack. It’s gross, it’s sticky, and it smells like a kid who forgot to brush their teeth.
My little brother had a hair booger so big, it looked like a spider had crawled into his hair.
I had a hair booger so bad, my teacher made me sit in the hallway.
My friend’s hair booger was so gross, it got stuck on my shirt.
