Thumbling 

Engrossed in your phone or device while being oblivious to the world

It's the worst when you're walking down a crowded sidewalk and you get stuck behind someone walking slowly because they're thumbling.

Thumbling 

The act of typing with only your thumbs on all typing devices, I.e. Computer keyboards and other devices through the learned behavior of texting on smaller devices such as cell phones.

Jason thumbled out his term papers on his computer keyboard to the amazement of his parents. "Mom, where are the bandaids? My thumbs are sore from thumbling!"

Cross-Thumbing 

Cross-Thumbing is a technique developed by Dr. Mark Ringwald PhD. and Dr. Nick Pollack PhD. at their video gaming ergonomic laboratories at Brandeis University. The technique is mostly applied when playing the Nazi Zombie segment of "Call of Duty: World at War". The technique consists of controlling the right thumb stick of an XBox 360 controller with one's left thumb while the right thumb is occupied with pressing one of the four buttons above the right thumb stick. The crossing over of the left thumb across the center of the controller, and in said gaming application is most useful while rebuilding barriers in the zombie level's windows to slow down the flow of zombies in the house. The technique allows the player to repair said barrier as well as aim and dispatch targets within the level.
