Assuming you're a guy and he clearly knows you can't kick his ass. Sadly, but often time in high school, it's all about being able to threaten someone to kick their ass and being capable of doing so to be entitled to make it run your way among guys. They're still kids. They get away with it as long as they don't actually do it.
Tell stuff like that to other students you don't like at college just because you don't like him, you're risking getting sued. Threatening to beat someone up can and have resulted in lawsuits.
