Meaning

Hey there — the katakana version of やっほー, with a cute/playful emphasis.

ヤッホー is the katakana spelling of やっほー, giving it a slightly different visual emphasis. The katakana version is often used in text-based communication where the writer wants the greeting to stand out visually or feel more pop/playful. In practice, both spellings are interchangeable, but katakana adds a stylistic flair common in manga, advertising, and social media.
