Extremely online
Etymology
The phrase spread in the mid-2010s among writers documenting internet culture (associated with the likes of Kaitlyn Tiffany and Katherine Miller) and gave the title to Taylor Lorenz’s 2023 history of the online creator economy. "Terminally online" is the sharper, more pejorative variant.
adjective · /ik-STREEM-lee ON-lyne/
So immersed in internet culture that it warps your sense of what is normal, urgent, or important to ordinary people.
What it names
It names a condition of over-fluency: the person who knows every meme, feud, and micro-discourse the moment it breaks, and has quietly lost the calibration for how little of it registers offline. The phrase is usually said with rueful self-awareness.
Example
He assumed everyone had strong feelings about the drama, which is how you know he’s extremely online.
Related idea
Milder than terminally online, which implies the immersion has become a genuine impairment rather than just a deep familiarity.
