The phrase refers to audio files, often short excerpts from the television series Dexter, specifically formatted for use as notification sounds on mobile devices operating with the Android operating system. These audio files alert the device user to incoming calls, messages, or other system notifications. The sound of Dexter Morgan’s theme music, or notable quotes from the show, are commonly used as these alerts.
The popularity stems from the series’ cult following and the desire for individualized device customization. The utilization of a specific show’s audio cue serves as a form of self-expression and association with a particular cultural product. Its availability reflects the open nature of the Android platform, which allows for easy customization of notification sounds, contrasting with systems that restrict such modifications.
