How do you deal with a guy teasing you?

I say “ok” or “ok whatever” or “oh come on, please?”

I think you probably need to be more specific if you want us to understand your situation. Ages, your gender, relationship, context, why is this teasing?, more details, etc…

What are you asking him to do?

I’m a serious person so I’ll immediately tell him the consequences if he didn’t do it… in joking manner, of course.

It sounds like he’s teasing in a flirty manner. I’d just laugh about it.

If he doesn’t do what you ask, no matter what his initial response was, then get in his face about it. And be prepared! He may like like you!

Why should he? How well do you know him? What do you want him to do?

Need much more detail to make any sensible answer.

Tease him back, hone your witty bantering skills. No man alive can outwit me. lol

Yell “That’s my purse! I don’t know you!” and kick him in the nuts.

Start avoiding them .
