Unfortunately, 'mayeng' isn't a widely recognized word in English. It doesn't have a standard definition. It might be a regional term or a newly coined word. Without context, it's impossible to determine a specific meaning. It could be slang or jargon within a particular community. If you encountered it somewhere, providing more information could help uncover its meaning. Perhaps it's similar to a blend of existing words, or maybe it's a proper noun.
