The Konami Code has been a helpful part of gaming and a fun trick for pop culture for over 30 years at this point. It first made its appearance in Gladius according to the Wikipedia page but was probably best-known thanks to Contra, even earning the name “Contra Code” at one point. It was practically necessary to beat Contra with and soon spread to dozens of games over the years with varying degrees of secrets, tricks, and Easter eggs. Outside of gaming, entering “up up down down left right left right B A” also grants access to several secrets around the internet too, spreading to sites like ESPN, Facebook, and Google over the years. But usually, it’s a little too cute for a government website to use.
