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

Moments after tweeting, "Drunk af going 120 drifting corners #[expletive]It YOLO," at 1:19 a.m. on Sept. 2, the car he was in slammed into a wall, and all five men in the car died. Four of the five died at the scene, reports said. "YOLO" stands for "You Only Live Once."

"YOLO" became a popular phrase 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 phrase has since been used by some to justify certain acts, such as drunk driving.

McKinness, who also went by Jew'elz and Inkyy, had just 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, Keith Conner, 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. 

According to reports, McKinness died at 1:40 a.m. in Ontario, Calif., after the 2005 Nissan Sentra he and his friends were in slammed into a wall and wound up in the backyard of a home.

The other passengers killed instantly were Dylan George, 20, of Ontario; Jonathan Watson, 21, of San Bernardino; and JaJuan Bennett, 23, of Rancho Cucamonga. It was unclear if McKinness or Watson was actually behind the wheel when the vehicle crashed.

The fifth passenger, Marquell Bogan, 23, died later at a nearby hospital, according to CBS News.
