Hancock is a 2008 superhero film starring Will Smith as a rough, reluctant hero who ends up in prison, where inmates test his patience. The Spanish line pondre tu cabeza en tu cola translates his crude threat literally and became the form shared on Spanish-language soundboards and meme pages. Clipped from that confrontation, it circulates separate from the plot as a short voice meme, kept alive because the wording is instantly quotable and Smith's weary tone fits many unrelated arguments and jokes.
