Keyboard Tourettes 

Occurs when someone becomes annoyed, bored, or simply cannot think of anything else to say in an online or texting conversation. The results can vary in characters and length, depending on how frustrated or bored the person is at that moment. This doesn't usually last long, only for one or two messages and is sometimes followed by an awkward moment where the person is unsure if that was a little too wierd or not.
