Have people you spar with regularly. If you jokingly talk shit to people who you are cool with, it becomes second nature and you start doing it as a reaction without even thinking about it. It becomes a reflex, I have zingers stockpiled in my mental files for almost everyone I meet, I can’t help myself anymore. I spent over 20 years in kitchens and I can’t help but to say something back if anyone dares to make fun of my speech. Everyone has something wrong with them. Never let someone talk down to you without making them pay for it. Ever. People rarely want to throw salt if they know it’s not for free.
