A sound/expression/phrase popularized by the Reggaeton artist Arcangel.

Often used to mark the end of a statement/verse/song, and to hype it. Occasionally combined with the hand gesture of holding a gun.

Almost all reggaeton artists have a oral sound combined with a epithet that they use in every song to declare that it's their work. See example.
It is therefore associated with Arcangel, but became a very popular expression for a period within the culture.
