Is this playfight or humiliation?

Lately my boyfriend started to show off his karate mma skills to me/ on me...
Randomly he starts boxing the air in front of me,"picking a fight" with me, lifting his leg near my head... with "wow look what i can do, if it was some bloke here Id smash his head"
And im like... wtf... are... you... doing?
He is like: "Im just joking around babes".
Uhm... Im confused and I dont like it. Its weird.
He thinks Im a man? He wants to fight me?
I dont understand whats going on. How to react to it. Why he does it to me? Somebody explain me this
Is this playfight or humiliation?
