The state of being while texting in which your brain is the god of spelling and grammar, but your thumb navigates a touchpad like a drunk walrus behind the wheel of a Corvette.
You: "Bro, I was texting Cindy that she took very aesthetic photos, but I spelled "aesthetic" like "assfart". Now she'll never suck my dick."

Me: "Being thumb dumb is the ultimate game-killer."
