I saw a preview of this about ten years ago on SKY, bravo I think, i don’t know if it was a dedicated movie, or a streamed movie, English language. From what I can remember the English or American school girls (supposedly teens) wished for something and either themselves or another school girl suffered (horror), it appeared to be some kind of anthology. It struck me as being quite gory and kind of funny.
The Craft?
Wishmaster 3 (2001)?
The Outing (1987)?
you said English language, but check out Wishing Stairs (Whispering Corridors 3) (2003), from South Korea. it also fits your description.
Thanks but none of the films are it.
