28 years ago I was accused of showing a "dirty" movie to 2 children that I still love to this day. Back then the parents had recorded it to a VCR tape... and I still want to clear my name on this: A teenage movie where at the beginning all the boys are standing around a high school (?) pool, and all we see are naked butts. I am not sure what the movie was even about, except high school life. After 28 years, I still have not found the name of the movie, but now we have internet! Please help me if you can!! That was the only part of nakedness that I can remember. I know this is stupid, but I really want to prove my case as it was their movie. Thank you for any help!!

We might need a little more to go on other than some guys standing around a pool.
