Twink

Twink is gay slang for a man who is usually (but not always) in his late teens to twenties whose traits may include a slim to average physique, a youthful and boyish appearance, and little or no body hair. The age range for twinks is generally considered to be from around 18 to 25 years old. Twink is used both as a neutral descriptor, which can be compared with bear, and as a pejorative.
