In Ntaratu, rimpak warpansunu "to shorten one's tongue", is used as a phrase meaning "suck up to superiors, try to seem more high-status than one is", referring to the annoying habit of native elites to replace their trills with retroflex flaps in imitation of the distinctive accent of Jalve speakers. A similar idiom is kuihek paryehenu, "brighten one's hair".
