See, No One Says “Cool” Anymore. That’s Such An Old Person Thing. Now We Say “Coral”, As In “That Nose Job Is So Coral
Pearl Krabs, as a character who belongs to the younger generation in Bikini Bottom, amusingly illustrates how slang changes over time and how it is often linked to youth culture. In this quote, she humorously rejects the word "cool" as old-fashioned, implying that it is something only "old people" would use. Instead, she proposes "coral" as the fashionable, modern term for expressing admiration.
This quote is a witty reference to the generational difference in language and how younger generations often invent their own distinctive slang to set themselves apart from their elders. It also reflects the humor in SpongeBob SquarePants and the way the show skillfully integrates real-life cultural phenomena into its fantastical underwater world.
