The act of shaving someone's head bald. A lot of
people think this is just using clippers to buzz their hair really
short, but they're not doing it right. A
real headshave consists of buzzing hair really
short and then using shaving cream and a razor to shave it clean. To the skin.
If someone says "oh look i'm shaving my head", ask them whether they'll use shaving cream. Most of the time, they'll say, "No, I don't want to be completely hairless!" Then you'll know you've found someone who thinks they're shaving their head, but they're just getting a buzzcut.
