Vegeta is one of the central characters in Dragon Ball, the long-running anime and manga series, and his proud, short-tempered personality has made him a favourite source of reaction clips online. The F-rank idea comes from the grading systems used in games and tier lists, where F marks the lowest possible result. Combined, the two ideas work perfectly for memes and edits: a beloved anime rival delivering the harshest grade possible. That simple, instantly readable joke is why the clip keeps appearing in gaming videos, tier lists, and roast edits.
