Nomenclature.
"μ² Scorpii" (Latinised to "Mu² Scorpii") is the star's Bayer designation.
In Tahiti, a traditional story is told of a brother and sister, named "Pipiri" and "Rehua", who flee their parents into the sky and become stars. Their parents call them "Pipiri ma" while chasing them into the sky: "ma" "with, and" is used after names to mean "et al." In one account, the children become Shaula and Lesath in the tip of the tail of Scorpio, and in another they become Mu² and Mu¹ Scorpii. (In a similar version of the story told in the Cook Islands, they become Omega¹ and Omega² Scorpii).
In 2016, the IAU organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN approved the name "Pipirima" for this star on 5 September 2017 (along with Xamidimura for its partner) and it is now so included in the List of IAU-approved Star Names.
In Chinese astronomy, Mu² Scorpii is called 尾宿增二.
