a cheese fettish, a pink fettish, or even a Facebook fettish.

The crazy out-of-control obsession with out-of-control hair! Usually, the upside down bowl, the Helmet Hair, the classic 70s fro, or the definitely-in-need-of-conditioner fro. People who suffer from The Fro Fettish are attracted to anyone who has a fro, and have the crazy urge to get their hands on that piece of hair.
Melissa: OMFG DID YOU SEE HIS FRO?
Kat: Not again, Melissa. You need to learn how to control your Fro Fettish; maybe go for guys with buzz cuts
Melissa: BUT HIS FRO IS SO BEAUTIFUL.
