Mít máslo na hlavě

Meaning: To have a guilty conscience or something to hide.

Literally: To have butter on your head

Example: “Proč se tak červenáš? Máš snad máslo na hlavě?” — Why are you blushing like that? A guilty conscience needs no accuser.

English equivalent: A guilty conscience needs no accuser

Origin: From an old saying shared across Central Europe: someone carrying butter on their head, perhaps stolen, should stay out of the sun, or it will melt and give them away. Dutch has wie boter op zijn hoofd heeft, moet uit de zon blijven, recorded from the 16th century, and German and Austrian forms say the same. Having butter on one's head is having a guilty conscience.
