Terminally Online
Etymology
Modeled on medical phrases like "terminally ill" and "chronically online," its close synonym. "Terminally" pushes the condition to its extreme, half-joking that it is incurable. The point is that heavy immersion doesn’t just consume time; it recalibrates judgment.
adjective · /TUR-min-uh-lee on-LYN/
So immersed in internet culture that your sense of what’s normal, important, or offensive has drifted far from how most people offline actually think.
What it names
It diagnoses a real distortion of perspective — mistaking the obsessions of a small, intense online world for the concerns of everyone — and is handy for checking whether a "huge controversy" exists beyond your feed.
Example
Only someone terminally online would think that meme feud was front-page news.
