The phrase represents a specific method of acquiring and installing a particular mobile game. It refers to obtaining the installation package (APK) and associated data files (OBB) for the 2K21 basketball simulation on Android devices, with the intention of playing the game without a constant internet connection. The files needed are downloaded manually instead of through the official Google Play Store.
This method allows users to bypass geographical restrictions, install the game on devices that may not be officially supported, or play without incurring data charges. Historically, downloading and installing applications via APK files and OBB data has been a common practice for Android users seeking greater control over their software and access to content unavailable through official channels.
