Shortened forms of the numbers from eleven to twenty, used by some musicians as a way of counting beats in music that has time signatures over ten beats per measure.

Fin, (another spelling of the name "Finn") is so incredibly hot, but despite his good looks he can be quite a handful. He is a bit "crazy" in many ways. First, he has a lot of energy, is athletic, and he's very outgoing. But "Finn" is even worse. he is running on the walls half the time. he is so energetic its crazy. But Fin has a humongous d.... it is Wild. fin is also probably trans and gay asf. but Finn is a cis straight male. BORING! (by the way, this is all hypothetical, and is describing traits of people with this name, not a single person)
Woah have you met that guy fin? he's really hot.
Yeah I have! I would like him more if he weren't so energetic, though.

Mud fin is when someone passes gas, emitting some fecal matter that gets flattened out between their butt cheeks, poking out of the crack like a shark fin.
