This guy has been making light jokes about me infront of the group am with , they are pretty harmless and he is repeating the same joke over and over , I always reply by agreeing and amplifying the fuck out of it and make others laugh about it too .

I never take digs at him because honestly I see him as beta who's ridiculing himself and it's not worth it

How would you guys handle this , should I keep laughing and having fun or I stop him with a more serious response ?
