The act of putting a small animal who is in the process of dying painfully out of their misery by grabbing it by the neck and swinging it around like a lasso.
Man...we was out floatin’ on the river fly fishin’ and we done saw a goose dyin in the snow on the bank so we rowed over to it and gave it the ‘ole Montana Neck Massage to put that thing out of its misery

When using the term "square" in that context, you're emphasizing not just the rigidity or uptightness of the person, but also implying a lack of intelligence or narrow-mindedness. It's a way of criticizing someone for being closed-minded or foolish in their thinking or actions. In this usage, "square neck" would indeed be a disparaging remark implying that the person's mentality is constrained and unintelligent.
In a Conversation Among Friends:
Friend 1: "I don't understand why anyone would want to try something new. Stick with what you know, right?"
Friend 2: "Wow, what a square neck thing to say. You're really limiting yourself."
In a Workplace Setting:
Colleague 1: "We've always done it this way, and it's worked fine. There's no need to change anything."
Colleague 2: "That's such a square neck approach. We should be open to new ideas and improvements."
In a Social Media Comment Thread:
Commenter 1: "People who listen to anything other than classic rock just don't appreciate real music."
Commenter 2: "Seriously? That's the most square neck comment I've seen all day. Musical taste is subjective, dude."
Person A: "Can you believe John thinks he's so smart just because he reads a few books? What a pretentious jerk."
Person B (interrupting): "Hey, ease up. Calling someone out for trying to educate themselves is a bit square neck, don't you think? Let's encourage learning, not tear it down."
Person A: "You're just a brainwashed fool for believing in politician X's policies. Can't you see how misguided and stupid you are?"
Person B (intervening): "Hold on a second. Attacking someone's beliefs like that is beyond square neck. Just because you disagree with person's politics doesn't mean you should insult their intelligence. Let's keep this discussion civil."

November 29 this is the day you grab someone you feel comfortable with.
Some people you could grab the neck of would be your boyfriend, girlfriend, best friend, side hoe, or even someone you have a thing with.
