A fictional medical doctor who smokes enormous amounts of marijuana (see def. of Jenkins) and frequently participates in stoner activities, including, but not limited to: disc golf, ultimate frisbee, hacky sack, hula hooping, devil sticks, juggling, hiking, bungee jumping, hang gliding, baking brownies. He also has a habit of prescribing Xanex to every one of his patients - which is amazing considering he's a chiropractor.
Dude, let's give Dr. Jenkins a call after work. I heard he's cold chillin at the park.
