annoyware: n. A type of shareware that frequently disrupts
normal program operation to display requests for payment to the
author in return for the ability to disable the request messages.
(Also called `nagware') The requests generally require user action
to acknowledge the message before normal operation is resumed and
are often tied to the most frequently used features of the software.
See also careware, charityware, crippleware, freeware,
FRS, guiltware, postcardware, and -ware; compare payware.
