Top Definition
It's the act of turning a seemingly normal sentence, or group of sentences, into gibberish by way of a lazy thumb on the touch-pad of a laptop. The lazy thumb refocuses the cursor to another portion of the sentence while the frenzied typist continues unknowingly. This normally comes off looking like someone communicating in their second language, or possible the experiment of the monkey and the typewriter.
