example: "man, she has such a sexy body but when she bent forward, I suddenly saw her huge tailfins hanging down like giant rhubarb leaves and I got frightened that these things might have teeth and eat up my dick"
another example:
Eric: Where´
s this guy from? He´s talking like some kinda alien.
Zac: "He´s from Finland".
Eric: "He seems a little gay to me"
Zac: "Yeah man, he´s a
real tail Fin (tailfin) if you know what I mean..."
