look up any word, like fluffer:
 
1.
gfln- girl from last night

mostly used in a derogatory tone. the gfln typically refers to a whore which may or may not have been a mistake to hook up with
"dude.. my gfln has been bugging the shit out of me today!"

"you shouldn't have tapped that bro.. you never know when your gfln will come back to haunt you"
