Okay, so eshay is a word that is mostly used in Australia among young people. It means someone who likes to wear a lot of sportswear and use slang words like "bruh" and "fam". Think of it like a special kind of fashion style and way of talking. Some people might use it to describe others in a negative way, but it's important to always be respectful and not judge people based on how they dress or talk. Does that make sense, little one?
