Besides a few technicalities, I don't come close to qualifying...which doesn't surprise me, as I am far from the player type, but never been much of a simp, although in my opinion adolescence and simping can kinda bleed together in those years, in minor levels only. Not sure of the validity of that list of 'DON"T DO', but did well with that too, probably could lighten up the sarcasm, according to this, but that's something I should do in general, not specifically with women. I also think some mutual joking or making fun is a healthy, amusing, constructive thing, whether in a relationship or not. What's not cute or attractive, and I know guys who do this, is just making fun of a girl who has no interest in responding, some guy I know does this, and it's unbearable to be around, it's like 6th grade in the present day. He'll just go on and on, any opportunity to take a cheap joke or line...very obnoxious.
As far as talking about exes, I am good on this one too, though I feel like some women can bait/test you with the 'ex' conversation, and see how you react. Like they want to see if you'll take the chance to go in on the ex, and give you a wide lane...ex. Her 'You met my ex one time right...'? Me: 'Maybe, once briefly' 'The fat one....(laughing)' Me: Stockier....something like that. Slandering the ex seems tacky and immature, and some sort of emotional trap. I can't see where both of us going in on the ex has any sort of constructive or advantageous conclusion.
Without some really egregious and compelling evidence of behavior, it's best to say as little as possible, or be as middle of the road as you can. I'll give an honest opinion if asked directly, but only for that purpose. All the simping stories are hilarious, we need some in here, documented cases of the guy who always tries this route with women, the slander the boyfriend/date/one night stand routine.
