Comedian and internet meme creator Young Busco has died at the age of 31.
The Californian funnyman – real name Brandon Moore – died in his sleep on Sunday.
His devastated mum Valerie Cooper confirmed the awful news in a Facebook post.
"My only child…. My faith will not falter!!!! Lord be my peace," she wrote.

In a separate post showing a picture of her with Busco, heartbroken Valerie wrote: "I can’t believe the earth is still moving when I feel as though my world has stopped…Lord be my peace."
Young Busco was the man behind the ‘What are those?’ meme, which came about when he mocked a police officer’s boots in a Vine.
His screaming quickly sparked a meme, with hundreds of thousands of followers being inspired to make their own versions of the ‘What are those?’ cultural moment.
Brandon was a father of five from Oakland, California, and had amassed nearly 50,000 Instagram followers over the last three years.

His original video, posted on the now defunct Vine platform, had nearly 40million views.
It even got included in the Marvel blockbuster film Black Panther.
But Brandon came to hate the success of his meme, telling Huffington Post in March 2018 that it made him "depressed".
"When I saw [the Black Panther scene], my girl was trying to record it in the theatre, he revealed at the time.
"I slapped the phone out of her hand, because I was like, ‘I don’t want to f**king be a part of this.’
"For real. Every time I see that s**t, I get depressed," he added.

Busco had been planning to release a comedy DVD earlier this year, and had set up a "nonprofit fundraising catering business" called Busco Bussdown.
He had turned his life around after spending periods of time in jail in his twenties, including a spell for violating the terms of his probation by being arrested for the transportation for sale of a controlled substance.
Brandon also spoke honestly about his regrets in putting out his Vine, saying he would have done it all differently in hindsight.
"I would’ve put my watermark on the video. I would’ve put my face on the video when I did it. I would’ve copyrighted it. I would’ve done a whole lot of s**t different," he told HuffPo.
"But like I said, I didn’t expect for it to do all of that. I didn’t know it was gonna do all that. So I didn’t know. It took off right underneath my feet. I didn’t know. And then like two weeks after I did it, I went to jail, so I really couldn’t do nothing, you know?"
According to local media, no cause of death has yet been confirmed.
