Moolack 

Somebody who thinks they know everything and know what they're talking about, when in all actuality, they know absolutely nothing. They tell everyone useless facts that they pulled out of their ass to try and sound smart. There is no convincing them that they are wrong.

Person 1: Did you know that if you eat poison oak leaves, you'll never get poison oak?

Person 2: Um... where the fuck did you hear that..

Person 1: uh... i read it.. in a book.

Person 2: Wow.. you're a fucking moolack.

Moolack 

A climbing area in Oregon

"From Eugene head east on HW 58, just before the town of Oakridge, take a left on Forest Service Road 19. Travel east a ways and take a right on Forest Service Road 1944. The road forks at that point take a left and drive to the Fisher Creek Trail. This is the access point for the climbs"

Let's go to Moolack and rip some cracks up.
