Get the ennedmug. EN is an acronym that stands for "Erect Nipples". It is a sensation that can happen to either a man or woman when they are cold or sexually aroused. Often one can spot a bad case of EN from across a room, especially if the person with it also suffers from a case of pancake nipples.
Guy 1: Man, i almost put my eyes out on my girlfriends nips last night
Guy 2: How the hell did that happen?
Guy 1: We were banging on top of the deep freeze and she had a wicked case of EN, i swear they were harder than a diamond in an ice storm!
