Scumbag DNA is a derivative of the classic Scumbag Steve meme, featuring a 3D model of a DNA double helix wearing the iconic brown-and-blue scumbag hat. First appearing on Reddit around 2011, this meme template is used to personify the frustrations of biology and genetic inheritance. Users typically use it to complain about inconvenient physical reactions, such as getting sick during a vacation or inheriting undesirable traits from parents. It serves as a humorous way to cope with the uncontrollable aspects of human nature and the perceived betrayals committed by one's own genetic code.
