How to punish a kid without screaming or touching?

TL;DR: what do you do with a kid who's too big to physically move to time out, and he's not just going to listen to you when you tell him to go to his room?I apologize for the click-baity title, but it sums up my predicament.A disclaimer right up front: I have never, and would never, hit my kids.My son's a great kid. He's funny, he's smart, he's kind. He's also quite stubborn, especially when he doesn't get his way. Most of the time when he doesn't get his way he whines and pouts a little bit, but nothing extraordinary for a 7 year old.But sometimes it's like last night. He got into a snit, and started getting uncharacteristically salty and rude with me.He's one of those kids that has a hard time pulling out of snits like this. I know, because I was exactly the same way as a kid. At a certain point, he's not even mad at the thing, he's mad because he wants to be mad, and he wants everything his way. Usually, the best thing for this is to give him space to cool off.But sometimes, when he's really wound up like this, he resists attempts to give him the space. If I try to leave the room, he follows me to continue arguing. If I send him to time out/his room, he refuses to go. When he was smaller, it was easy to pick him up and plunk him down in time out. But now that he's 7...I can still do it, but I feel like it's getting to the point where I shouldn't, and that it sends the wrong message that physical force is how you get what you want. Not to mention that soon he's going to be too big to physically move.The only other thing I have in my toolkit is screaming. Now, I don't scream at my kids, mostly because my mom did that to me when I was a kid (like, nose to nose, flecks of spittle), and I hated it. It's not productive and just makes you scared of the parent. I can certainly see where it would be effective in at least getting him to leave the room so he can calm down, but at the price of making both of us feel awful?So what should I do? Revoking of privilege after privilege to get compliance? via /r/Parenting http://bit.ly/2weQFuJ
