boot fin

The fin created on one side of your hair/head when you vomit (boot) from drinking too much and then sleep in a pool of it. The fin formation is the result of it drying and creating the ultimate hair spiker.

Man, look at Tim—he's going to have a boot fin in the morning.

Is that hair mousse or a boot fin?

Yesterday I woke up with a boot fin and couldn't remember how I got it.
