An antiquated tradition left over from the early days before tickets and infolines for raves. Map Point was the place where you went to buy a map to the location of the rave (rather than the more modern concept of buying a
ticket then calling the infoline.) which was also buying your
ticket. It is
still frequently used, although in conjunction with tickets and infolines.
Raver A: Did you hear about that rave on the 18th?
Raver B: Yeah, I'm not going though cause it's on the map point system so it will be a
pain to get to.
