DJ Mustard goes nuts in the video for his latest Cold Summer single “Know My Name.”

Featuring Rich the Kid and RJ on the track, “Know My Name” finds Mustard in a straightjacket, looking bewildered and upset in what looks like an abandoned hospital.

Rich is also in the building, but he doesn’t have to worry about a straightjacket. Instead, he’s more concerned with stuntin’.

“I’m a boss, I might flex on a bitch,” he raps. “I ain’t lying, spend a grip on my wrist / If she bad I might take her to the red carpet / Bought a car, now I’m tryin’ to learn how to start it.”

The video keeps the creepy imagery going as RJ raps with a magnifying glass on his blinged-out grill and as ghostly models pop up throughout.

“Know My Name” follows videos for “Want Her” featuring YG and Quavo and “Don’t Hurt Me” featuring Nicki Minaj and Jeremih.
