The tune is all about a woman who-you guessed it-flatlines his heart because of how attractive she is. "Dang, girl, look at you/ Stopping me in my boots/ What's a country boy to do, but say/ Uh uh," Swindell sings in the song's opening verse.

The chorus picks up on the song's title, and finds Swindell about to have a figurative heart attack after looking at the woman. "Somebody better call a doctor/ She's a little heart stopper/ I'm talking breaker breaker one-niner/ She's a flatliner, oh she's a flatliner," he sings.

Elsewhere in the song, Swindell and Bentley joke around about how they would even approach such a woman. Easily said and done, just sing her a tune.
