Is there such thing as goth posers?

Okay I just moved bck to PA from AZ after living there bout a yr and found out my beat friend went goth. She wears all black clothes, pentagrams, dyed her hair black, wears black eyeliner&lipstick, does drugs, cheats on her bf with guys&&girls, burns incense, and listens to bands like nine inch nails, korn, and rites of spring. She hangs out with guys tht wear all black and dye their hair black, wear big baggy pants with chains, and beat up emo/scene kids for fun. Me&my friend/ex-friend (idk if we're friends anymore) are 13 and in7th grade but her goth friends are anywhere from 7th-11th grade. so I was wondering is there such thing as goth posers, since there are emo/scene posers, and is she one. btw she is rlly mean to most of us preps (but she's still sorta nice with me) & calls all the not goth groups gay posers& conformists& losers. So are there such things as goth posers&&is she one?
