fgirl 

This is a girl many people know, I’m sure you know of an fgirl (fuck-girl). She’s a girl who likes to fuck a lot of people, and many people know about it. This is why they call her an fgirl, same type of thing as an fboy (fuck-boy).

“Wow! I heard Jennifer fucked the whole football team! She’s such an fgirl these days.”

fgirl 

An fgirl is like a fuckboy, they tend to mess with his feelings and not his penis

The girl I smashed last night is an fgirl. She kept saying I had a lil dick and made me feel ashamed.

fagirl 

A fangirl whose main obsession is homosexual men - generally derived from their love of male/male slash, or pairings/shipping. Often, said pairings are wildly out of character or non-canon, but this isn't always the case. A portmanteau of fag and fangirl.

Guy 1: Her deviantart is mostly filled with Harry/Malfoy slash.

Guy 2: Wait, wait, wait. Mostly?

Guy 1: There's one or two Sirius/Lupin fanfics.

Guy 2: Dear God... She must be a fagirl.
