What strategies other than what OP said I can use to make her feel like shit?

First off, I should clarify that "treating her like shit" = "making her feel inferior." When a woman feels inferior to a man, she subconsciously decides that his SMV is above her own.

A man who makes a woman feel inferior has demonstrated higher value, by covertly communicating his ability to replace her. Be careful not to confuse this with telling a chick that you're more valuable than her. Ironically, doing so would have the opposite effect: She would feel superior to you. Always demonstrate, never explicate.

So how do you treat her like shit / demonstrate your higher value / demonstrate her lower value?

In the beginning stages of attraction, this is done by covertly communicating your ability to pursue other options. She must feel like she's replaceable and must therefore compete for your time and attention.

Stare deep into the eyes of the bitch in the bar you're flirting with, but if she turns away (like even for a second) then you better start flirting with her cute friend. Otherwise in her mind you're just a nice guy who will do whatever she wants you to do.

For girls you haven't plated yet, a good way to make them feel like shit through texting is by objectigying them. Make her feel like you want to use her, like she's a slut who you just want to fuck really hard and don't feel like investing too much time into pursuing. She'll view your high risk behavior as a willingness to leave her if she doesn't comply - to her this means you have other options you're pursuing.

Treat women like replaceable sluts and they'll try to win your attention by acting like whores. Otherwise, they'll lose the "competition" for the man who they perceive as high value.
