Describes a person who, when typing a text message using a single hand, is able to use both thumbs with equal ease.
I spent a month with my right hand in a cast and had to do all of my texting with my left hand. When I took the cast off, I realized that all of the practice with my left thumb had made me ambitextrous. Now I can type just as fast with either thumb.
