Aspiring rapper Ervin McKinness, 21, did not know how telling his latest tweet was over Labor Day weekend.

Moments after writing, "Drunk af going 120 drifting corners #[expletive]It YOLO," at 1:19 am on September 2, the car he was in slammed into a wall, and all five men in the car died. Four out of five of the men died at the scene.

Mckinness, who also went by Jew'elz and Inkyy, had signed a record deal, according to Vibe.

"He was trying to go out in the music business and stuff. He was getting there already and he was up there. He already had made a couple songs too, and then this stuff happened," his cousin told The Daily Bulletin. McKinness actually already had a video for one of his songs, titled, "Dreams," which was released on his YouTube channel, InkyyTV, in April.

But after his tweet, the driver of the car ran a red light and lost control. According to the Huffington Post, McKinness was not the driver.

'YOLO' has become a popular phrase among young adults, after rapper Drake released a song earlier this year titled "The Motto." In it, he raps, "You only live once, that's the motto [expletive] yolo."

The term has since been used to justify certain acts that may not be deemed the most responsible, such as drunk driving. McKinness died at 1:40am in Ontario, Calif., after the 2005 Nissan Sentra he and his friends were in ended up in the backyard of a home.

The other men who died instantly are Dylan George, 20, of Ontario; Jonathan Watson, 21, of San Bernardino; and JaJuan Bennett, 23, of Rancho Cucamonga. Watson was reportedly the driver.

According to CBS News, Marquell Bogan, 23, died later at a nearby hospital.
