Etymology: "Phattest" is the superlative of "phat", so the real story belongs to the base word. "Phat" began as a deliberate misspelling of "fat", the ordinary English adjective, and it carried the slang sense of something excellent or admirable rather than anything literally heavy. The swap of "ph" for "f" is the kind of playful respelling that African American Vernacular English has long used to mark words as its own. The word therefore keeps a quiet joke at its core: a term for largeness was respelled to signal a new, positive meaning. The superlative "phattest" follows the regular English pattern of adding "-est" to mean "most of all", so it simply means the coolest or best of everything in its group.
