In Rick Riordan's "The Lost Hero," the speaker sarcastically addresses a comment about someone's mother being a 'rainbow goddess,' reflecting an attitude that questions traditional notions of masculinity. The humor in the exchange suggests that embracing a colorful, vibrant identity is not at odds with being strong or macho. Instead, it emphasizes that characteristics often seen as soft or gentle can coexist with traditional masculinity.

This dialogue highlights the book's playful approach to themes of identity and self-acceptance. By juxtaposing the idea of rainbows, often associated with positivity and beauty, against the conventional concept of macho, Riordan invites readers to reconsider stereotypes and celebrate diverse expressions of strength.
