What is the ‘septum arms’ trend taking over TikTok?

‘Septum arms’ are the newest TikTok meme that came about from a misunderstanding on a recent TikTok video making fun of septum piercings; while the phrase doesn’t have any actual meaning, TikTokers have made it their mission to give it one…or several.

What are 'septum arms' on TikTok?

TikTok is one of those delightfully odd places where phrases take on new meaning, largely because folks who use the platform are forced to adapt their way of talking to avoid being banned from the app. Phrases like “unalived” for “killed” have wormed their way into everyday vernacular because of this algorithm issue.

As fascinating as the shift in language is, sometimes TikTok comes up with some truly bizarre trends and memes that take on a life of their own. This is very much the case in the instance of ‘septum arms,’ a budding phenomenon that came about from a misunderstanding on a TikTok video about a woman’s arms where someone made a crude comment. That being said, no one discussing this new trend names the TikToker who started the conversation in the first place!

Overall, the consensus is that ‘septum arms’ as a phrase is nonsensical. It doesn’t mean anything, especially given the fact that the septum is a dividing wall or membrane, for things like your nostrils or heart. The arms don’t have any septums on them, so this is a classic case of a made-up phrase morphing into something else.

Speculation about the meaning of ‘septum arms’ on TikTok

Even though we know that the ‘septum arms’ TikTok trend doesn’t actually mean anything, people on the social media app are all trying to come up with a consensus on what it could mean, with a few possibilities taking the charge.

Some people are suggesting that it means that the person’s arms are larger above the elbow than below.

Other people say that it’s the squish that comes from the arm when you lie down.

There are still others who simply define it as “chubby arms.”

And those who say that the origin of the term is more complex than that, say that it relates to self-harm scars on people’s arms.

Another user, Megs (@themeganrhiann), did a fit check on her TikTok account and said in the overlay of her video, “after finding out what ‘septum arms’ are I am no longer wearing this jacket today” as she shows off her beautiful pink maxi dress. The aforementioned white jacket is pulled down to her elbows as she poses for the camera and puts on sunglasses.
