Cara is the Irish word for 'friend'. Not sure if thats what was intended or is just a coincidence.

Male genital organ in few of the balkan languages (spelled with K), pronounced the same. So, there's that too.

Also the Spanish words for "face" (no me gusta tu cara, boludo) and "expensive and female" (esa computadora es re cara, boludo). https://en.wiktionary.org/wiki/cara tells us it also has meanings in Aragonese, Asturian, Catalan, Crimean Tatar, French, Galician, Indonesian, Italian, Latvian, and another couple dozen languages.
