Seen it years back, almost 100% tiffani amber thiessen was in it (not main character), remember being 3 or 4 girls being good friends and one of them accidentally gets killed by another then one hooks up with a guy who somehow they end up killing another one of her friends by getting her to drink a cup of bleach as she thinks its fresh o.j. I think and near the end he attempts to blow up the school and she somehow stops him and I think kills him and she is covered in like black dirt and gives her remaining friend a kiss on the cheek.. that's all I remember, been bugging me for years, help would be appreciated sincerely :)
