Mrkrstft comes from a user-generated soundboard, where it was uploaded without any stated source, show or artist credit, and its sub-second length suggests it was clipped for quick reuse rather than recorded as a standalone effect. Short anonymous uploads like this typically spread when editors hunting for fresh transition stings stumble across them, then keep them in rotation because an unrecognisable blip fits anywhere without carrying unwanted associations. With only a handful of plays so far, it remains an obscure pick, which is exactly why early adopters favour it for edits that need something nobody has heard before.
