ORIGIN OF 4lifers

There is a new Anglo-Saxon slang term, which has appeared on TikTok at this time and as we all know it has its own vocabulary and its own phraseology.

It is full of strange words and phrases, which if you do not belong to the so-called Z generation, chances are that you do not know the meaning that most of them have.

In this case, they can be family members, siblings, cousins, friends or co-workers, whether it’s the love of your life or just as friends to support each other whenever needed, it doesn’t really matter.

The one rule is that they must be with you for life and hence the word “4lifers”. This phrase went viral on TikTok thanks to a video posted by a user named @boobackbaby in which a producer and rapper named Lucki says, “What are we, 4lifers!”

After this, many other users started using @boobackbaby’s sound clip in their TikTok videos, and at the moment it has become one of the most popular phrases on that social network.


The term “4lifers” can also be used shortened to just “4L”. It means “for life,” meaning forever. The 4 stands for “for” and the L stands for “life”.
So, if you see someone use this “4L” thing on TikTok, then you know what they mean.
