The song is an up-tempo number in which the narrator describes the intensity of his lover as being comparable to the explosion of a firecracker.
Music video
A music video was released to promote the single, directed by Peter Zavadil. In the video, Josh Turner is seen pulling up to a fireworks outlet. While he is inside shopping, mixed in are scenes of a young man, flirting with the girl at the counter, played by Miss Kentucky Teen USA 2005, Sarah Bryan Withers. Turner is shown performing the song on an outdoor stage in parts of the video.
The video is shot in Kimball, Tennessee, near Jasper and South Pittsburg.
