My girlfriend said she wanted to try and get rid of her love handles. I said she would look fucking stupid without any ears.
What do you mean by losing her ears? Do you believe this with women in general?
It's a joke. Women are just sexual objects and they don't have a right to be equal with men in this century
I honestly do not get the joke but I feel like what you're saying has a little bit of a sexist undertone, so I do warn you that it is not a great thing to say to your girlfriend or to any other person, really. What I would suggest you do is to try to say sorry to your girlfriend and maybe try and gift her a gym membership or a yoga class if she wants to still pursue trying to lose weight and losing her "love handles".
