If this doesn't make sense to you, I apologize and will try to explain it to non-US folks.
During the Superbowl, one of the most watched events in the US, during the half time event musician Kendrick Lamar performed his hit "Not Like Us", which was a response to a rap battle between him and Drake.
That's a whole other fun drama you should read about.
When he actually said, "Say Drake..."
I was just in disbelief that it was actually happening. It was an amazing moment. However I had friends that didn't follow the biggest song of last year and I had to explain it to them. Doesn't hit as hard if you're just learning about it.
