red flag?

so this could just be a joke but I'm chatting to this guy and he jokes if I thought about eating something unhealthy he'd slap my face to stop me thinking about it. kinda concerning so I joked back saying such violence for one cookie. he just goes better than putting it in your gob and going on your hips. erm..? am I just paranoid or shall I say adiós

Update!

thank you all so much for your messages, I enjoyed having a chuckle reading through them all! good news! I ditched him. and I ate an Oreo after 🤷🏻‍♀️
