A contributor or lurker who, out of envy, spite or misplaced rectitude, combs through another contributor's list of words in order to deliberately give each one a "Down" thumb without considering any potential usefulness such words might have.
-- "Santa Claus? I don't get it, Kurt, who is against Santa Claus?"
-- "Poor ol' Burt, it looks like you've been the victim of the dumb thumb down. Check out your other entries to see if you got flamed there, too."

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."
