SLS
An Acronym meaning
Sudden Leaving Syndrome.

Sufferers tend to have the attention span of a fish and leave conversations or internet chat. When not given attention or a discussion is not about oneself

But you can only apply SLS to a sufferer when the given person leaves unannounced or a very quick "bye" giving no time to initiate their departure.
Dave: "so.. Emily how's life?"
Emily: "Great at the moment, bit bored with scho..."

-During Emily's reply she quickly Turns around and leaves completely unannounced and unepected during conversation.

Another Example of SLS can be seen in Instant messengers

11:16AM Emily Says: "Hi Dave"
