"Scruff" literally means the back of one's neck, but "Scruffy" can also mean shabby or untidy. Sometimes "scruff" or "stubble" is referred to as unkempt facial hair that makes a person look like he needs to be cleaned up. If you're a semi-regular shaver, you're probably more than familiar with stubble. It's the prickly beard and moustache growth that sprouts up after some time has gone by since your last shave (depending on how fast your hair grows). Many people believe shaving causes hair to grow back thicker, darker and faster. It's not true. Shaving does, however, alter the tip shape of the re-grown hair, which may initially change the way the hair feels as it grows back. In some circles, a little bit of stubble can be an attractive look, coming across as rugged, rebellious or artistic. But as sexy as it might be from across the room, a stubble-studded close-up encounter with a loved one might be more pain than it's worth.
