What's the meaning of DISALLOW_FUN in Android's source code?

Question

From http://developer.android.com/reference/android/os/UserManager.html, we can find a weird string variable named DISALLOW_FUN, which Specifies if the user is not allowed to have fun.

However, I cannot understand what it means.

Any explanation?

Answer 1

It's an attempt to make Android compatible with Windows Phone users.

Answer 2

AFAIK, it is an Easter egg, along the lines of GRAVITY_DEATH_STAR_I and many other similar jokes in the SDK.
