“Butter someone up”in other languages

Same idea, different pictures

English spreads the praise on thick, like butter. Polish beats the drum for someone, podbijać bębenka, making a lot of noise in their honor.

Chinese pats the horse's rump, 拍马屁. A popular story traces it to Mongol riders praising each other's horses with a pat, whatever the horse was really like. Korean puts the person on an airplane, 비행기를 태우다: lay on enough praise and they're flying.
