Many custom launcher apps, such as Nova or Apex, allow you to hide apps from the app drawer - don't know about Samsung's launcher, but if you install one of these you'll get that option.
You can always remove an app from your home screen - a long press on the app icon should bring up the option to remove it.
If you don't want to run the app either you can disable it: Settings > Apps, select the app, select disable.
There's no way of hiding it from the apps menu apart from uninstalling it.
If none of those is the answer, could you post again and explain exactly what you mean by hiding the app?
