The Hot Scale meme, specifically the Universal Hot Crazy Scale, gained mainstream fame through the TV show How I Met Your Mother, where Barney Stinson explains the correlation between a person's attractiveness and their level of insanity. The Vicky Mendoza Diagonal serves as the threshold for acceptable behavior within the chart. Since its television debut in 2007, the graph has been adapted by the internet into a versatile meme format used to compare any two conflicting traits across various subjects. It remains a staple of internet culture for its relatable and often controversial take on social relationships and dating dynamics.
