The act of circling the street blocks in a city in the search of a parking spot.
When driving around in a city, you intend on finding a parking spot on the street (usual a metered spot) close to your destination. So you first circle around the block that the destination is located. If none is found, you advance to the next block and circle around it. This is repeated till your successful in finding a parking spot. In reality, this is not a game, it's frustrating.

The antithesis of a cock block, a game block occurs when one's girlfriend/wife/spouse prevents him from playing video games from his friends. Most of the time this occurs because the girl needs phone time.
