vaakasuorana

I’m not sure what "vaakasuorana" refers to. Could you specify whether it is a place, a cultural practice, a linguistic term, a person, or something else? Providing context, a language background (e.g., Malagasy), or any source would help me write a concise, neutral, wiki-style article under 300 words. If you’d like, I can also create a fictional encyclopedia-style entry for a fictional concept with that name.
