One wonders whether Akk. pīštu ‘insult’ may be related to PC *pašˁ- ‘crime, transgression’ rather than derived from the somewhat ephemeral *wapāšu (AHw. 1459, CAD U-W 402).
From Hurrian pe/idarže “enclosure for bulls”, a transparent derivate from pe/idari “bull” (BGH 319) with the nominal suffix -že (Giorgieri 2000:202, Wegner 2007:55).
