The phrase comes from Japanese dialogue associated with Paragus, the father of Broly in the Dragon Ball franchise, and the source tags link the clip directly to that character. Anata mo douzo is a common polite expression in Japanese, roughly inviting someone else to take or try something as well. Short anime voice lines like this circulate on soundboards because the original context is removed, leaving only the courteous delivery. That makes the clip reusable for offers, reactions and edits far beyond Dragon Ball fandom.
