Your status is changed to that option.

You can add other status messages to the default list.
On the Jabber home page, tap your availability status.
Tap the + (plus sign) in the upper-right corner.
Enter a custom status and tap the default color status setting you’d like to associate with it.
Tap Save.
The new custom status becomes your current status and is available in the future as a default status option.
