Someone is threatening to come in my house and beat me up?

[Jarren bh!Figuring]

I'm a senior in high school, a guy, 17 years old. Basically, this other guy really really hates me, because he thinks I'm gay. Which is completely untrue but I really don't want to waste my time dealing with rumors. Anyways, last week on twitter he started calling me out and publicly humiliating me and calling me every possible homosexual slander you could think of. I ignored him for the longest time. Then my friends jumped in and told him to back up, and that he's worthless and alls he does is smoke pot (which is true). I then moved on with my life after he ended up embarrassing himself and making himself look like an ass. Well this weekend, my parents are out of town, and he's threatening to come in my house, beat me up, kill me, whatever you can think of. Are you kidding me? He honestly never stops. Should I text him and confront him about how stupid he's being and call my parents? What would I do if this kid actually did find a way into my house?
