RALPHSTACHE 

When a girl shaves her butthole but misses a few hairs

I was balls deep and noticed her Ralphstache.

rapestache 

noun 1) Obscure facial hair atop the lips of males often identified as serial rapists. 2) The sad result seen on faces of pubescent boys in their failed attempt to grow a mustache

15-year-old Joseph did not shave for 3 months, and that is why he now has a rapestache.

Rashstache 

When a person(most likely female), attempts to remove unwanted upper-lip facial hair with a lotion or chemical remover(like Nair), and either leaves it on too long, or experiences an allergic reaction.

Today, I wanted to look really good for my date. I was a little self-conscious, so I decided to use Nair on my upper lip just in case I had a female mustache. Unfortunately, it turns out I'm allergic to Nair. Now I DO have a mustache. A rashstache.
