The 'Nathaniel B' meme originated from a viral freestyle rap battle video uploaded to TikTok and Twitter in mid-2022, featuring a student named Prince roasting his opponent with the confusingly specific line, 'You're probably Nathaniel B.' The phrase immediately caught fire across the internet due to its seemingly nonsensical nature and perfect comedic delivery, leading millions to ask: Who is Nathaniel B? It was eventually revealed that the name referred to the opponent’s younger brother, but the mystery and the specific cadence of the roast turned it into a staple of Gen Z humor, typically used to mock someone's uncool or 'NPC' behavior.
