Hey bro!
I'm all too familiar with these, having been bullied and publicly humiliated through high school. Even as I make my way to college I encounter those from time to time.
One key mindset to internalize is that everything is a battle of frames. Especially with guys who try to tool you. (There are legitimately cool guys out there who are not constantly trying to impose their frames. These guys almost never tool other guys though)
Once I understood that anything can be a power move, I begun forcing myself to be very aware. I would replay conversations in my head and anayse the exact moment a power move was imposed on me and what I did not do to counter it. Then I would tell myself that next time I'm not letting it slide.
Now, as to examples, there are SO many. Infinite I would say. Could be the way a guy grabs your shoulder in a supposedly friendly way but makes it seem like he's totally dominating you. Or it could be way more direct like an insult or a not-so-friendly joke. Could be someone trying to make you move from a spot. Anything, really. You'll know it when deep down you feel like you lost and a bit dominated.
How to counter them?
In a nutshell,
--> Don't move, react or extend any sort of effort when someone tries to make you move. Just stay still, flash them a Damon Salvatore smirk and shake your head no and get back to business
--> For direct attacks, you want to address them. As in, "Hey, what you just said came across as really rude", "I don't care if you did not mean it, it came across that way" Don't be afraid to look like you have a thin skin. You would be surprised how people will respect the shit of you when you let it known clearly that they offended you and that you don't like it.
--> Have a set of comebacks ready for direct and semi direct insults or mean jokes. Chase's article on comebacks covers it all
--> Keep meditating on frame control so that you see it coming as it comes. It will remove the element of surprise that a lot of frame control attacks have and will give you time to formulate an appropriate response.
--> Be friendly with as many people as you can so that, in case of a public confrontation, you have an army to back you up. If the crowd is on your side, the battle is already won.
