Boy slaying is when a girl strategically flirts and teases enough that a guy falls for her. Once he's hooked and she can get whatever she wants from him (attention, free dinner, steamy makeouts), the game is over and she never talks to him again--except possibly to keep stringing him along enough to continue receiving attention from him, to boost her ego. Often times the boys are strung along for even months, unknowingly being slayed until they become a hardened shell of who they once were.
