First, "GTA" is obviously Grand Theft Auto, the video game series. The "+4" likely refers to GTA IV, which is Grand Theft Auto IV. Then there's "playerpedrpf" – that looks like a technical term, maybe related to character models or the game's code. "Backup" and "upd" could stand for backup and update, perhaps. So, putting that together, it seems like a story involving GTA IV, modifications to the player character's model (playerped.rpf), creating a backup, and applying an update.
