VSCO girl means: (A girl or woman who embraces) a trend or subculture of the late 2010s and early 2020s, characterized by heavy use of social media and relaxed, beachy fashion.. It is internet-era slang, commonly seen on TikTok, Discord, Reddit or X. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. If your teen uses it, context will usually make the intent clear. A short, curious question about where they heard it is usually all that is needed to know whether to follow up.
