Mustache ride or just another meme?

Earlier today I stopped at a local sandwich shop/deli to get food on my way into work.  A woman standing next to me in line had a tattoo of a mustache on her pointer finger on her right hand.  You have probably seen people on the internet in multiple memes with a drawing or tattoo of a mustache on their finger that looks like this:

Well, when I saw the woman's tattoo, my first thought was "Did she really get that tattooed to her finger?".  My second thought was a bit more tasteless.  I wondered (and wanted to ask the woman, but decided I shouldn't) if a woman with that tattoo masturbates with said finger, does that count as a mustache ride?  Technically I think it does qualify.

After reading that you probably understand why I didn't ask the lady.  Keep in mind that I am 35 as of this writing and I noticed the woman appeared to be about my age or maybe even 10 years older.  It seemed odd that a woman of that age would get a tattoo like that, but then again, maybe she just really likes mustache rides.
