Kosmo!

Kosmo! is a fictional greeting, exclamation, or name, often associated with a sense of enthusiasm, surprise, or futurism. It's frequently employed in science fiction, comics, and other forms of speculative fiction as a lighthearted or intentionally retro-futuristic expression. The exact meaning and usage are highly context-dependent and generally left ambiguous, allowing for flexibility in its application. Its distinctive sound and capitalization contribute to its memorable and somewhat whimsical quality. The word has no widely recognized formal definition or etymological origin outside of its appearances in fictional works, relying solely on contextual clues for interpretation. It is primarily used as a stylistic element to evoke a particular tone or atmosphere.
