Well humor is subjective, but beyond how I feel personally, uhhh yeah people do it all the time and it never gets called out as body shaming or any such thing, nobody cares. Bald, fat, ugly, small dick, all are fair game, especially if you have at least one other undesirable trait. Andrew Tate is balding, Trump is fat and has a little dick, anyone who has a large vehicle also has a small dick, anyone who owns guns has a small dick, the British have a small dick, etc, it’s everywhere and everyone else seems to love it.
