I am trying to find the title of this movie. It was about some dorky kid who spilled something or drank something and turned into some kind of mutant thing and started killing off everyone who abused him. It was a really bad movie but I need to see it again.

The kicker here is that I just watched "Sliver", and one of the girls in the movie was watching this movie on T.V. for a couple of seconds. The scene is where the guy was mopping the pool area and accidentely puts the mop in the pool and everyone starts yelling at him.

I'm sure someone knows the name of this movie.

Thanks in advance...
