He threw a cold shoulder on the idea
Posted: September 5, 2012 Filed under: ACTION, BODY PARTS | Tags: blended idioms, cold shoulder, cold water, expressioins, malaphors, mixed idioms, snub 1 CommentClassic mix-up of “threw cold water on” (negative about something) and “turn a cold shoulder” (snub someone). Both expressions indicate negativity; “cold water” is negativity toward something and “cold shoulder” negativity toward someone. In this case, perhaps the speaker not only disliked the idea but the person expressing the idea as well?
