Bon Clay, also known as Bentham and Mr. 2, is a flamboyant character from One Piece who begins as an enemy of Luffy before becoming one of his most loyal and affectionate friends. The Spanish phrase 'por qué somos amiguis' plays on that unlikely bond, using the cute, informal word 'amiguis' instead of 'amigos' to make the friendship sound warm and deliberately silly. Spanish-speaking fans reuse the line in edits, memes and reaction videos whenever two characters, or two real friends, share an unexpectedly close bond.
