The male narrator pursues his cheating significant other upon seeing her with another man, telling her that she has "gone and broke the wrong heart, baby / And drove me redneck crazy." It is in the key of B-flat major with an approximate tempo of 73 beats per minute and a main chord pattern of Gm7-E♭-F.
Billy Dukes of Taste of Country gave the song two and a half stars out of five, writing that "one expects a song with such a name to be a little more fun, but predictable country rock ballad production holds the three-and-a-half minute cut back." Dukes described Farr's performance as "sincere," but added that "he’s let down by an ordinary lyric and unexceptional arrangement." Jon Freeman of Country Weekly praised the song in his review of the album, saying that "it's a bitter, almost scary account of a jilted man stalking his ex and her new guy. It's so messy and human, and it's got a chorus that'll stay with you." Emily Yahr of The Washington Post was critical of the song's message, calling it a "disturbing song" and "glorified stalker anthem".
