(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.
