You Put Someone Horns on Its Head

This is a German figure of speech. “Jemandem Hörner aufsetzten” – You put someone horns on its head. This has the meaning that you cheat your partner. So who has the horns on the head is the dupe.

Besides the woman you can read: Though you have everything but your husband is cheating on you.

Next to the man you can read: A gorgeous antlers adorns your forehead. You are indeed a good-looking guy. But you have very little brain.
