rip to a real one

An expression of acknowledgement and respect to someone or something, especially after a loss. In its most serious context it can reference a real dead person, but is used more often in trivial matters such as when a favorite restaurant closes down.
Etymology consists of RIP, an acronym/initialism of Rest In Peace, and real one, someone or something that is great or significant.

Person 1: Did you hear that the pub closed down?
Person 2: Nooo, their Irish nachos were the bomb! Rip to a real one.
