You can't hurt their egos unless you're much higher status then them. They can only become vulnerable to attitudes of those they desperately want to fuck and gold dig, otherwise succubi's egos can't be affected by anything an ordinary man can say or do. Just give up on this one, I know it's hard to simply bear it but trying to fight it is nothing but trouble. Avoid them as much as you can and think of doing something that makes you feel better instead.
I know experiencing their assholery will always hurt but the best way to cope is to disengage and limit your exposure to their shit to an absolute minimum. If you have no choice but to deal with them at work then streamline and optimize all of your interactions with them into brief, technical, detached, professional, to the point exchanges while projecting an air of the most unshakeable indifference towards all things that aren't related to getting the work done. If whatever business they may have with you can be finished quickly and efficiently they'll probably shut the fuck up on their own and leave you alone because in the end cutting the bullshit and getting things done as fast as possible benefits everyone.
These days people are much more interested in looking at their retardphones than interacting with anyone. They still socialize and play the workplace games but they do it more out of implicit expectations and perceived obligations than for fun. Truth is in 99% of cases succubi would rather go back to their cubicle to watch Netflix than flirt with Chad at the water cooler. The trick is to give them the free, consequence-less option to fuck off. The hard part is actually getting them to choose that option.
If you outright tell them to fuck off they won't and it's only going to get worse since they'll try to use all the other workers against you. If you try to go with a simulated cordial normie routine they won't fuck off due to oversocialized female impulses compelling them to engage in all available petty social maneuvering opportunities even thought they hate you. Usually staying exceptionally dissociated, focused only on the essential tasks and doing it until they notice and choose to pursue the wide open option to fuck off seems to be the best method. It requires the patience of a saint, a thick skin and the ability to deal with the pain inside but it worked for me.
Disclaimer, note that getting people to mostly leave me alone didn't make being around them all easy and peaceful. AftPost too long. Click here to view the full text.
