Double-Tubing

When someone is sitting in front large screen watching a YouTube video while simultaneously surfing YouTube on a laptop, phone, or tablet. This is Double-Tubing. It's great when deep-diving into a particular subject.

I always enjoy double-tubing when I need extra stimulation, or when I'm obsessed with a particular subject.

Double Tubing

The act of opening two web browsers to watch two youtube videos at the same time, or to watch a vid while uploading one.

Girl: you gotta see that new video on youtube!
Boy: but i'm uploading something important!
Girl: then start double tubing!
