a (slang) Originating from surfer culture and/or Southern California. An expressive term to mean something is of large magnitude, either good or bad, and sometimes both. e.g. "That wave was burly!" (meaning it was large, dangerous and difficult to ride). "This hike is going to be burly, but worth it because there is good body surfing at that beach." (meaning the hike is going to be hard work).
