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.

An individual who creates a bruh moment VERY frequently. They are usually dumb people in general, and still say "pisghetti" and "aminal". This word is also used against somebody who thinks mayonnaise is spicy.

shark fin

A mountain bike feature leading into a jump with a lip at a 45 degree angle. Leads to a sideways jump and requires the rider to twist his bike mid-air to prepare for the landing. The feature sticks out of the ground like the fin of a shark that's crossing the trail.

Rider 1: Dude, see me send the shark fin??
Rider 2: Totally. That was sick, bro!

punch their fins out

Destroy the fins on someones surfboard. Specifically if that someone is ruining your surf and not a native.

Originated from bloodborn Aussie's living off the Gold Coast.

These beta cucks just dropped in on our swell. They better have 2nd generation grandparents from the Gold Coast, or we'll punch their fins out.
