hanging fin

When a small child pulls their penis out for no apparent reason.

Did you see that kid in the lunch line? When the salsa music came on he totally started hanging fin.

Fin Flap

Shaking your dick to remove remaining droplets of fluid

I just went to the bathroom, but there was still piss on my dick after I went, so I had to fin flap to get it off

fin laden

The final product after DNA from a shark mixes with Bin Laden's body and radiation from the Fukishima plant in Japan. A mix between shark, terrorist, and badass super villain.

First summer of the sharks, then 9/11, and I just had a Fin Laden sighting!

*actually this is a form of f-in sucked, but the person who originally sent it in an email forgot and put the - in the wrong place, therefore creating a new word: fin-sucked*

so...been fin-sucked lately?
