Three best friends return for their high school reunion intent on righting all the wrongs done to them in high school — by either fucking, marrying, or killing their tormentors.

Sounds like an interesting plot, but the use of such vulgar language turned me off.

You need better word choices, believe me, I know.

First of all, I would turn off the "F" bombs. I think it's off-putting. Second, you need to hone in. As other people have commented, it's hard to tell the genre, and to be honest the term "killing" their tormenters in this sense brings up images of school shootings.
