Students at Tennessee State University are being warned that a wolf whistle at a fellow student could get them expelled.
Under a new policy at the Nashville-based school, "whistling in a suggestive manner" will no longer be tolerated, The College Fix reports.
The university also reportedly frowns on "suggestive or insulting sounds," "suggestive or obscene gestures," "unnecessary touching or brushing against the body," and jokes about sex.
The directives are part of the university's attempt to put the kibosh on all forms of sexual harassment.
