e/Horsefeathers

Information
has gloss	eng: "Horsefeathers" is a term used to say that something is nonsense, often used as an exclamation after hearing something which one totally disagrees with. It is supposed to imply that an idea is as silly or as unbelievable as horses having feathers. The word is fairly new in origin; its first recorded use was in 1927 (with the Marx Brothers' film being released in 1932 of a similar name), perhaps as a polite replacement for "horseshit." "Bull butter" is a similar euphemism, alluding to the absurdity as a bull producing butter, and at the same time avoiding the profanity of "BS".
