What else can i say to get back at this kid?

Tell him youll steal his diamonds

Reported

Reported, not funny and if he happens to harm himself or kill himself, your posts will be turned over to the police and you can and will get charged

But I think you are a troll

How about growing up a bit before someone with some real sense stomps your guts into apple butter and not the good stuff from the farmers market either.

You can say "I'm sorry for acting like an immature, childish jackass that has nothing better to do with his time than bullying somebody that's probably getting a good laugh out of it. The reason I do this is because I'm insecure and I have to put other people down to feel better about myself."
