If you haven't had an intrusive thought in a while, I've got a brand new one for you right here! I know, you can thank me later.
Or rather, thank vlogger and science whiz Hank Green, who took it upon himself to explain to the world what exactly chin dimples are - and everyone wishes he had kept it to himself.
Hank was replying to one TikToker who screwed his face to show off his chin dimples and innocently asked: "What is this thing". Well I bet he regrets asking now.
Green explained that chin dimples are caused by your mentalis muscle.
"It's in your chin and it is very weird", he began. "You have identified correctly a weird muscle. Well done."
Explaining how the mentalis muscle worked, Green told his followers: "Almost every muscle in your body connects a bone to another bone. Your bones yank on each other, that's how you move.
"There are other muscles, like sphincters, that just yank on themselves. The heart is a totally different kind of muscle - it yanks on itself to pump your blood around."

So far, so good.
Green continued: "In our faces, we have a bunch of muscles that do not connect to other bones"."
"You can tell this, right? Like, all the movement that faces do, we that we can talk and emote and stuff - we're not yanking on bones here. We're yanking on skin."
This is where things start to get kind of gross.
The social media star explained that the mentalis muscle connects from bone to skin, hence the dimples it makes on your skin when you flex it.
"You can see the mentalis here, doing an absolutely wild thing, sticking all of its little muscle fibres into your skin", he added sharing a horrific picture of the muscle growing from the skull.
"When you contract that muscle, it yanks. It yanks on the skin and makes those little dimples.
"It's a little weird. We're all made out of meat", he swiftly concluded.
Feeling a little bit uneasy knowing that those purple fibres are living in your chin? You're not the only one.
Hanks followers took to the comments to share their horror and disgust, complaining that they probably could have gone their whole lives without knowing this information.
One distressed viewer wrote: "Thanks! Never speak of this again."
"This makes me nauseous", complained another.
"I am so upset that I now know this information", penned a third.
And a fourth added: "I'm sorry but I REALLY hate knowing this and it's gonna haunt me for a long time."
Not everyone took it so hard, though. In fact, one user actually found a positive spin to put on it.
"So what I'm hearing is that we all have an invisible sole patch?" he asked.
Pretty cool when you put it that way, I guess.
