the meetup world refers to whatever vrchat instance everyone is currently hanging out in. It's usually friends+ which means you can join the instance by joining a friend who is already in there, no invites or requests required as long as you know someone., if you're brand new you won't know anyone so add one of the anchors then make some more friends inside so you can join if all the anchors are offline.

unless you mean a world made by/for /vrg/, there's heaps of those but no list since you can see any worlds a friend has created in the same social menu.
