In a restaurant setting this is when a party is sat at a table by staff, but then the party delays ordering for excessively long periods of time, not related to waiting for others or any valid reason. Usually this is accompanied by the server's frequent check-ins to encourage them to place an order. Reverse campers are not malicious, but rather may be enveloped in conversation with company, or in less-frequent scenarios, may lack the social awareness to remedy their behavior.

This is in contrast with camping, which refers to a party either delaying paying the bill, or paying the bill and choosing to occupy the table for a long period afterward.
Server: "Man that couple over there sat down 30 minutes ago and still haven't opened their menus or ordered drinks."
Bartender: "Yeah, they're reverse camping."
