Does hairy in "Big Hairy Audacious Goals" mean "hazardous and frightening"?

Context:I have mentioned to some that I don’t feel motivated to get to the gym, but I didn’t feel motivated before the treadmill desk either, so I wouldn’t count that as a problem of the treadmill desk. I have added in some pushups to my workday. No set number just a few pushups every now and then to change things up. Got the idea from “The One Push-Up Challenge” which talked about small changes making a big impact. I already have enough BHAGs (Big Hairy Audacious Goals) that I am working on. None of my co-workers have walked in on me doing push-ups, they still get a chuckle when they come down and see me walking and working but they are super supportive!
