Why do stoners like clippers?

Why do people who use marijuana, or stoners as they're commonly referred to, tend to favor the use of clippers, which are often used for grooming and trimming? Is there a specific connection between the relaxation or mood-altering effects of marijuana and the need for personal grooming or cleanliness? Or is it simply a coincidence that these two activities often occur in tandem? Furthermore, what role might the cultural context or societal norms play in this perceived correlation? And how do stoners themselves perceive the significance of clippers in their routine?
