'Bone smashing' is a dangerous and pseudoscientific 'looksmaxxing' technique promoted in some incel-adjacent corners of the internet, in which users hit their facial bones with hammers or other objects in the belief that the resulting micro-fractures will heal into more attractive features. It is medically unsound and causes serious harm. If your teen mentions or jokes about it, take it seriously and start a conversation about where the content is coming from and the body image pressures young men face online.

For ESL learners
'Bone smashing' is a dangerous and pseudoscientific facial-modification trend promoted in some 'looksmaxxing' online communities (incel-adjacent), in which adherents strike their facial bones believing the resulting micro-fractures will heal into more attractive features. Medical authorities warn it causes lasting injury. Register: niche internet, harmful subculture. In formal writing, frame critically and note the medical consensus against it. A common learner mistake is to treat it as ordinary fitness slang; it is a health-warning topic.

“There has been much hand-wringing in the media over “bone smashing”, for example, an extreme technique that involves taking a hammer to your face to promote more “manly” regrowth when the bones repair, but little evidence that anyone is actually doing it. “The majority of the posts that you see about looksmaxxing are not serious,” he says, adding that he promotes only softmaxxing.”

For specific readers
Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.

- looksmaxxing68%
The pseudoscience-adjacent pursuit of maximum physical attractiveness — mewing, facial exercises, beard oils, bone-smashing memes. Primarily male-internet culture.
- smashing61%
The breaking or destruction of (something brittle) in a violent manner.
- negative looksmaxxing60%
Negative looksmaxxing is the opposite of optimization — the accumulation of choices and habits that actively worsen your physical appearance. It might be unintentional (sleep deprivation, poor diet, stress) or a deliberate rejection of mainstream beauty standards. In looksmaxxing community discourse, negative looksmaxxing is used analytically to identify what's dragging someone's appearance down, almost like a debugging process. More broadly it gets applied humorously to describe someone who seems to be on a self-sabotage arc, making every possible choice against their own aesthetic interests.
- looksmaxxing fail60%
A looksmaxxing fail is when your attempt to optimize your appearance goes wrong — spectacularly or subtly. Maybe the haircut you researched for three hours looks worse in person. Maybe the aggressive skincare routine you stack-tested from forum advice nuked your moisture barrier. Maybe the jawline exercises gave you a weird asymmetry. The term is applied with ruthless humor, both in first-person confessions and in roasting others. Looksmaxxing fails are content gold because they expose the gap between the obsessive research culture and the messy reality of actual human bodies.
