Twink chaser usually refers to someone who is attracted to twink-identified partners, or gay men with slender builds, little facial hair, and a youthful appearance.
“Chaser” can be neutral, teasing, self-descriptive, or critical depending on context. Someone might jokingly call themselves a twink chaser simply because twinks are their type. But chaser can also imply that the person is overly fixated on the category rather than the individual. Some people dislike the term for this reason.
