What is "takpirtu"

Takpirtu or Takpertu, inscribed tak-pir-tú and as a gloss to the term šu-gur-gur- meš, and literally meaning “wiping,” from kupurru, “to wipe, rub,” or more generally ““to perform a wiping rite,” were Mesopotamian purification rituals whose oldest attestations go back to the Old Babylonian period. It was an integral part of the Bīt rimki and Bīt salā’ mê rituals and may have been a cleansing rite in its own right as it is listed separately in the Exorcists Manual, perhaps in the form of tak-pir-tú nussētiq, burnt offerings.
