Meet Bryan Silva, a 23-year-old Vine superstar who has nearly half a million followers. His catchphrase is a fake gun noise, "gratata".
For some reason a lot of people really seem to love this "gratata" thing.
Inspired by Silva, a bunch of people have incorporated the noise into their own videos. Like these guys:
Silva considers himself a bodybuilder and an aspiring rapper. Which he might use to justify his offensive use of the n-word alongside a lot of sexually explicit language.
He said that alongside hard work, he's famous because he also has a name that "literally gets stuck inside your head."
Silva recently appeared on the World Star Hip Hop website to address his haters. The video has been seen over 1 million times. "Haters make you famous," he told Complex.
The satirical news website Huzlers reported last month that Silva had been murdered as punishment for his offensive language, which sparked a series of tweets using the hashtag #RIPBryanSilva.
But this was, of course, a hoax and he has posted on Vine many times since. Which means you can expect plenty more of this.
