face-tubing
When you're on the London Underground and you pretend you're not a human being by staring at your phone like it's the only thing that matters.
I face-tubed through the entire tube ride. I didn't even notice the guy who spilled his coffee on me.
During my commute, I face-tubed so much I missed my stop. Classic.
I was face-tubing when my friend waved at me. I didn't even see him. What a loser.
