Eshay is a slang term used to describe a contemporary Australian youth subculture that is particularly prominent in major cities like Sydney. The name is believed to derive from Pig Latin for "lad" (" adlay "), and the subculture is often associated with working-class youth, Australian drill and rap music, and a specific style of street fashion.

The aesthetic is defined by a uniform of designer and brand-name sportswear, which can include polo shirts, puffer vests or jackets, and athletic shorts from brands like Nike, Tommy Hilfiger, Ralph Lauren, and Nautica. A particularly iconic element of the look is the Nike Air Max Plus sneaker, commonly known as "TNs." The style is often completed with accessories like a bumbag (fanny pack) worn across the chest. Eshays are stereotypically associated with a tough, hypermasculine demeanor, anti-social behavior in public spaces like train stations, and a background in street graffiti culture.

Key garments include polo shirts, puffer vests, and athletic shorts from brands such as Tommy Hilfiger, Ralph Lauren, and Nautica. The look is heavily reliant on specific accessories that act as status signifiers. These typically include Gucci caps, Oakley sunglasses, and a bumbag (fanny pack) worn across the chest. The most iconic element of the uniform is the footwear, almost invariably a pair of Nike Air Max Plus sneakers, commonly known as "TNs."

The Eshay subculture is stereotypically associated with a tough, hypermasculine demeanor and anti-social behavior, often involving groups congregating in public spaces like parks and train stations. A distinctive feature of the group is its use of slang derived from Pig Latin. For example, "eshay" itself is a play on the Pig Latin for "yes," while other common terms include "adlay" (lad), "illchay" (chill), and "eetswa" (sweet). Musically, the subculture is closely linked to the Australian drill and rap scene, with prominent artists associated with the style including OneFour, Spanian, and Sydney Youngins.
