The 'He Boomed Me' meme originated from a 2018 tweet by NBA insider Shams Charania, quoting LeBron James's reaction to being dunked on by rookie Jayson Tatum during the Eastern Conference Finals. The quote featured LeBron repeating 'He’s so good' four times before expressing a desire to train with Tatum in the off-season. The absurdity and repetitive nature of the quote quickly turned it into a viral copypasta used to describe being outplayed or 'owned' in any competitive context, from sports to video games. It serves as a humorous way to acknowledge a rival's skill while leaning into the dramatic irony of a crushing defeat.
