Pantyfan

pantyfan

:
a fan who wets his/her panties over the person or persons after which they fan. (Not a derogatory term.)

1. "omg omg omg i love you omg omg i want to have your babies omg," the pantyfan said.
2. noun: David Boreanaz has many pantyfans.
verb: Lots of people pantyfan Spike.

I personally believe this term is actually more useful than "fangirl" and "fanboy", because it's all gender inclusive, and because the word itself shows the craziness of the obsession. The origin of the term can be found in this podcast, if you listen to minutes 3.12 through 8.34. Just because she's my best friend in the whole world doesn't mean she doesn't get a good idea from time to time.

There are subdivisions of the word, as described in the podcast:
bloomer fan, cotton pantyfan, boxers fan, thong fan

Pantyfan, illustrated, totally stealable and without credit, because no one cares, as long as you teach a penguin to say pantyfan:
Pimp, Señora.
