köken: From Late Latin cauma (“heat of the midday sun”), from Ancient Greek καῦμα (kaûma, “heat, especially of the sun”), from καίω (kaíō, “to burn”). Possibly through the intermediate of Italian calma, although the word was found in Ibero-Romance as early as in Italian.
köken: Uncertain. According to Bańkowski, a variation of pimpać, from German das ist mir pimpe (“I don't give a fuck about this”). First attested in 1900.
