The 'What The Hell Is This and Why Did My Grandson Like It' meme is a satirical take on the widening generational gap regarding internet humor. It typically characterizes the confusion of a grandparent or older adult who stumbles upon surreal, deep-fried, or 'brain rot' memes that make sense only to younger digital natives. Originating from the aesthetics of Facebook 'old people' posts, the phrase has become a go-to reaction for anything particularly bizarre or incomprehensible on the timeline. It effectively highlights how quickly internet culture evolves, leaving anyone over a certain age feeling completely disconnected from what the youth consider funny.
