There's not much information available about this video, other than what the mom who made it tells us, which is mainly that she's Christian, and she's very upset about the lyrics to a song called "Norf Norf" by a rapper named Vince Staples.

So upset that she spends a good portion of the video reciting the words to the song and straight up bawling.

Obviously she hasn't listened to a lot of rap in her life (surprise!) because her mind has been blown, and not in a good way.
