a code word for the Morning After Pill, used by girls who need to keep last nights antics a secret. Useful if your on the phone to a friend and theres somebody within hearing distance thats not supposed to know what you've been upto. for example, if your having an affair or your parents are around. The word 'map' makes girls feel less slutty than they actually are.
girl 1: so what did you get upto last night...?
girl2: ah nothing much really, can you come with me to buy a map...
