What is kissed horizontally?

"Kissed horizontally" isn't a widely recognized term or phrase in English. It doesn’t refer to a specific concept in common language or pop culture as of my last update. It might be something specific to a niche group, an inside joke, a specialized context, or simply a creative expression.

If it comes from a particular source—like a song, a book, a meme, or a specific cultural context—it would help to have more details to provide a more accurate explanation or analysis. Let me know if there's additional context or if it's part of a larger story or backdrop.
