Origin: The origin of the idiom “cool your jets” is rooted in aviation and became popular in the mid-20th century. Jets, particularly jet engines, can get extremely hot and require cooling to function properly. Telling someone to “cool their jets” is metaphorically advising them to reduce their excitement or agitation, similar to how a jet engine needs to cool down to prevent overheating. The phrase effectively conveys the idea of calming down and taking a moment to relax before proceeding.
