chivheti
means the Occidental culture (chiRumbi) or generally anything that does not relate to customary ways of Chivanhu (African traditional culture).
Note: Keep in mind that the word Vheti means the English language; it doesn't matter whether it's en-US, en-GB, or whatever. But the word muvheti is similar to murungu (or mukiwa) which means of European descent. And finally, the plural for murungu is varungu.
