Extremely Online

It means conducting your life online as much as possible so you have minimal human contact.

You shop online, you work from home courtesy the office VPN, you speak to your clients/boss/colleagues online, you chat with friends online, you spend a good part of your day on social media sites, you stream, you watch online videos, and you speak to your family through SMS. Some say being "extremely online" is when you manage to go a day without opening your mouth. 

Historical perspective: According to the Daily Dot, the phrase Extremely Online dates back to 2014. It means to be familiar, even obsessed, with the things everyone is talking about. In this instance, “online” usually means “on Twitter,” and “everyone” is just a small core of media professionals and influencers who are all fluent in the same discussion.
