Nash Grier -- the most followed person on Vine -- billowed out a homophobic slur so loud and angry it is truly shocking.
The 16-year-old posted the video in April -- then quickly deleted it. It features a snippet from a TV commercial about HIV. Grier clearly took issue with the message.
The reason it just surfaced -- Tyler Oakley, another social media star, got his hands on it and was appalled enough to blast it out.
Grier has since taken to Twitter to apologize.
