"100 Proof" is a song recorded by American country artist Kellie Pickler. It was released on April 16, 2012, and served as the second single from the album of the same name. It was written by Leslie Satcher and James T. Slater, the same writers that wrote the album's first single "Tough". "100 Proof" uses an analogy between love and alcohol levels, as if its addictive. The song was Pickler's first to not reach the Top 40 on the Billboard Hot Country Songs chart, peaking at number 50 instead.
