<human>: Can you give me the gist of the text in a nutshell?

I'm dating this guy who sort of 'teases' me to be funny, which i'm not really used to. Anyway recently some of the comments he's been making have been a bit out of line and I don't really know how to react. 

I feel almost like he's testing me to see how much shit I'll put up with. 

Eg. of his 'fun' teasing.

- constantly ripping on my university, saying it's worse than his.

- making fun of me for the part of town i'm from.

- saying i'd gotten sloppy when I wore track pants in front of him

- making fun of me for being younger than him.. ('ohh it's probably befoer you're time', 'you're part of the swag generation')

more malicious teasing:

- asking if I was autistic because I do crosswords and word jumbles for fun (they're fun alright! I like them!)

- saying 'I should have gotten drunk before you came over. That way I'd be able to put up with you.'

He apologised for that last comment and said he was just joking because I was like, 'What the fuck dude! Don't say that to me.'

This is not the sort of 'fun' teasing I've experienced in previous relationships and am sort of lost as to how to react. If it's in good spirit than I don't really mind and can dish out a bit to him as well but once he starts calling me names I'm just like, 'what the fuck. How old are we?'

Thoughts? Reactions? Do you tease? Are you teased? Is it fun? Is it mean? Who even knows.
<bot>: The guy I'm dating teases me and it's getting meaner. What do I do. What would *you* do?
