The official way to "disable" an app (usually bloatware or other system-apps) was only introduced with Android 4.0. Before that, apps could be "frozen" with e.g. Titanium Backup on rooted devices. Users which started with Android 4.0 or higher thus might never have been confronted with the "freeze" term, and consequentially missing the freeze-app – as you can see e.g. with How can I permanently disable (not uninstall) a stock app?.
