pornstache
n.— «You may be annoyed with the recent tendency to use “porn mustache,” or “pornstache,” to describe any arrangement of lip hair.…Here’s how to distinguish the true porn mustache: —It’s thick and unkempt. No pencil-thin or highly stylized trims. —It goes down the corners of the mouth, but not too far. If it ranges way down the chin, it’s probably a Fu Manchu, which is a whole different bag of bristles. —It’s not pretty.» —“So long, mustache—hello, pornstache” by Bill Dawson Star Tribune (Minneapolis) Jan. 15, 2006.
