It's the kind of taunt worthy of a flag for excessive celebration.
But the man confronting the camera is no NFL star; he's a suburban Dallas police officer.
After allegedly kneeing, then cursing and cuffing a teenage suspect, Officer Disraeli Arnold boasts to the video being recorded by the arrested teen's friend.
"You got it on tape?" the officer shouts, before giving his name and badge number. "Arnold ... Six fifty-four!"
The Hurst Police Department announced Monday that Arnold has been put on leave pending an ongoing internal affairs investigation.
"Obviously, this is not behavior that the City of Hurst and the Hurst Police Department promotes or condones in any way," the department wrote on its Facebook page. "We strive to build a stronger, safer community through our work around the city and will continue to do so through appropriate action. We appreciate everyone's thoughts and continued civil discourse as the investigation is conducted."
CBS 11 (KTVT-TV) was the first to publish the edited video clips. According to its story, Andrew Rodriguez, 17, and two friends were being questioned as suspicious people last week when officers learned Rodriguez was wanted for a previous trespassing charge.
When Rodriguez walked away to call his mother, an unidentified Hurst officer began wrestling with the teen in an effort to handcuff him. One of Rodriguez's friends had begun recording video with his phone when Officer Arnold rushed in from off camera and allegedly knocked Rodriguez's head to the ground.
"Move and die," Arnold shouts, then repeats the phrase and curses.
In a longer version of the video posted to YouTube (language warning), Arnold continues his verbal assault even after Rodriguez is handcuffed.
"Blink wrong," he challenges the teen as he is being put in a patrol car.
Rodriguez was charged with resisting arrest. His mother tells CBS 11 she may seek legal action against the officer.
