Offset was hanging out at a Target in Sandy Springs, Georgia (just outside of Atlanta) shopping for a baby stroller.
Eighteen-year-old Junior Gibbons was there, too ... and spotted the rapper shopping. He thought it was a pretty cool moment, took out his phone to record a selfie video, but when he asked, "What up, Offset?" ... he didn't get the response he wanted.
Check out the video to see Offset's reaction!
Offset slammed this kid’s phone to the ground, screamed at him, and then walked out of the store.
Junior says he went to the cops and filed a police report on Friday. He simply wants Offset to pay for a new phone.
