Noun (From nipple + whiplash) The tugging of the breast when a nursing baby turns to look at something behind him/her while securely latched on. When a baby decides not to take a break from nursing and suddenly and energetically jerks her head around to look up down and all around the room (still firmly latched onto your breast)
Baby dad burst into the room suddenly while I was nursing and I got a severe niplash.
