Shark Fin

The act in which a girl gives you blue balls and you are so horny that you jerk off on the drive home.

Boy 1: The principals daughter gave me blue balls so bad I had to rub one off on the way home.
Boy 2: That’s called a shark fin!

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!

fin baby

What crazy owners call their pet fish, similar to crazy owners calling their cats and dogs “fur babies.”

My landlord doesn’t allow dogs and cats, so I got myself a fin baby instead.
