weird creep rant (TW?)

I'm not sure what im supposed to do on here but I've seen people just talk about random things so :3

There's this guy who ive known for a while whos been harassing me. But unlike some people im not a complete suck up so I bullied him until he eventually blocked me. But after he had blocked me he's been going after other people.. 

He's being weird asf and always talking about sex and how his dick is "so big" even though he told me that his dick was small after i half jokingly said small dicks were cuter.... ERRMM

Here are some things he has said:

"I have DID.. that was my horny side" (after he harassed me)

"Im a future serial killer"

"I want to be raped by a woman"

"Im gonna do this to you when you're asleep"

"Im gonna eat you"

"Give me cuddles NOW"

"anyways ima take a nap cause i need my little nappy cause im a little toddler"

HE IS 16 IM GONNA KMS. How can I drive him to suicide :P
