The evil eye, ’eyn hora, is pretty cross cultural. The phrase in Yiddish is keyn ’eyn-hora 'no evil-eye; knock on wood'. In Italian the sign to make to counter the malocchio is the cornuto 'the horns' (index and pinkie stretched out with middle and ring finger curled under covered by thumb) or the fica 'the fig' (thumb between the index and middle finger). The evil eye can be the envious glance of somebody (usually considered a witch). Bad mojo. Ptui, ptui, ptui. &c.
