I stick my lower lip out when in thought. Do you?

When in thought, or reading, or concentrating, I stick my lower lip out so that it covers my upper lip. In fact, I pull the upper lip into my mouth, inside the lower jaw. It seems strange, but I don’t know if it is. Is there a name for it?

It’s involuntary, and I’ve done it all my life. My mother commented that one of my nephews does the same thing.

I do pursing and pouting of my lips when I read, paint or letter. I chew my inner cheeks, as well.
I don’t know if it has a name.

I migrate to a classic open mouth, slack-jawed, stare-ahead when thinking deeply, or concentrating like on a video game, so you’re luckier than me.

Focus face. That’s what I’m calling it absent anything else.

In thought or focus of whatever kind my face more freezes into the last position. For really intense consideration I tend to freeze basically my entire body.

The reverse, sort of. I bite at my lower lip.

No, I minimize physical movement when in thought.

I stroke my facial hair. When a thought hits, I cackle. Most amusing.

The one I’m more familiar with (as in, have read others having too) is slightly sticking your tongue out. I could see sticking out the lower lip being similar.

I chew on my tongue. When I’m caffeine deprived I chew on the inside of my cheeks.

Have you ever hurt yourself? Chewed enough to be painful or to bleed?

I chew on my tongue (not enough to bleed). Supposedly I even did this as an infant.

I furrow my brow. Forehead slips southward. Looks like a relief map of Turkmenistan. When I’m done, I often have to manually un-furrow. Sometimes it’s painful. My wife thinks it’s odd.

Not enough to bleed but enough to be a little sore the next day.
