Hello everyone. I think, that movie was American and took place in american suburb, but I'm not sure. 3 boys are suffering from one bully from their school. One boy is fat and dark haired and the only scene that I remember well is the one where the bully exposes this fat guy naked in front of all the school (no, it's not some perverted movie, it's just that the scene was very memorable). I've seen it on tv in 1998-2000. Thanks for your attention!
