My Boyfriend 18M won't stop calling Me 18F a foid

To start, I dont consider myself chronically online or anything like that so with this term and others I don't fully understand the meaning. We have been together for a few months now, at the beginning of our relationship and even recently he wouldn't stop calling himself a chud (literally multiple times every day) which I know is self derogatory so I try to get him to stop.

As of very recent, probably the past 2 weeks he keeps calling me a foid almost everyday and he keeps saying I'm the foid to his chud. Foid from my understanding is also negative so I don't like him calling me one and also calling himself a chud. He even does it in front of our friends which embarrasses me.

Is there anything I can do? How do I get him to stop? Thanks in advance.
