Treadwell

(n.) An effeminate gay man, generally without protrusive body hair, who enjoys the company of a bear. More commonly known as a chaser. This usage is more common in the Pacific Northwest and the Great Lakes regions of the United States. Derived from the name of late American video-journalist and environmental activist Timothy Treadwell (1957-2003), who enjoyed living among bears.

I caught Josh hanging around the bar on Bear's Night. He's such a Treadwell.
