Ruminating on "Headless" concepts

Today afternoon, within a span of 2 hours, I have heard the term 'headless' being put ahead of multiple words. For e.g. headless system, headless app, headless service and finally headless UI testing !

A headless system is essentially a system with no monitor and IO components (mouse, keyboard, etc.).
A headless app is an application that does not have a UI to interact with - analogous to background demon threads, etc. A headless service only has backend logic and no frontend UI.

So essentially the team headless is used to address the concept of not having any user interface. So what does headless UI testing mean?
Check out PhantomJS - a headless testing Webkit that makes this possible. A good article summarizing this concept is available here
