Curious about this as well since neither of these recently-updated articles from the NYTimes-owned (meta)review site The Wirecutter mention being able to find any bone-conduction headphones they liked.
These were my first ideas as well, albeit in reverse order ;) Having thought a bit more now, I might prefer yet another option -- what about "twirling"? (like "in circles" or "your hair")
Here's a post, though not from Alicorn, that has some info that may be of interest: http://lesswrong.com/lw/453/procedural_knowledge_gaps/3i49
Apparently it's supposed to link here.
FYI, this is the original source of that top line you're quoting: http://asofterworld.com/index.php?id=740
(the alt-text might[n't] also be noteworthy to you, which reads "Understanding is for terrorists.")
Feel free to comment -- since only the user you're replying to (and anyone that has chosen to subscribe to updates for that specific post) is notified, you don't need to fear being a distraction to masses of people who might no longer care.
Perhaps the article you read was Yvain's The Virtue of Silence?

I strongly dislike this. The head seems too ornate and the outline reminds me of so-called "tribal" tattoos, which seems low status. The body being subtly asymmetrical is a slight annoyance as well and with the owl now being centered in the image I think the subtitle should be too.
