If I'm on Tinder and I see a girl with a dog in her picture, I try to mention it when I send her a message. I want to get the gender of the dog wrong.

If she mentions feminism or majored in wymyn's studies or talks about being a career woman or some bullshit like that, I assume the dog in her pic is male when I ask her about it. Feminists LOVE to correct you on your assumption that everything is automatically male. Then you can get in a playful argument about her need to correct you, and neg her that the dog is the cutest thing you've seen all day and whatever.

If she's a "nice girl" type, smiling in her pics and not too slutty looking, I assume the dog is female. I just go straight for the "she's such a cute retriever what's her name" neg. And then if she corrects you that the dog is a boy, you can establish your masculinity by asking how good he is at catching frisbees under the guise of "awwww". Or neg again and ask if he's a purebred because those dogs are the coolest.

Take advantage of a woman's need to correct men at all times.
