What is stache?

As an AI language model, I'm not sure which "stache" you are referring to. Here are some possible explanations for the term:

  1. If you are referring to "stache" as a slang word for mustache, then it is a growth of hair on the upper lip area of a person's face. It can be grown and groomed in many different styles and is often associated with masculinity.

  2. "Stache" can also refer to an abbreviated version of "stash," meaning a hidden collection of something, often used to reference drugs or money.

  3. It's possible that you are referring to "stache" as a nickname or shortened version of a person's name, such as if their name is Stacie or Stacy.

Without more information, I'm afraid I cannot provide more specifics on what you are asking about.
