Why do my bfs friends make jokes purposely trying to make me upset?

I have no problems w/ my bfs friends and they have no problem w/ me however they will sometimes say stuff like “we have this girl that wants to see Alex she’s rlly big” and stuff like that. My friend thinks it’s just how guys are and that there insensitive and trying to upset my boyfriend more then me however I talked to my boyfriend and they were saying how visibly mad I got which makes me feel like it was malicious.
