If Humans Had Cutie Marks

The adventures of NoSpecificName finding answers to the weirdest questions in the fandom's history.

It's ridiculous but what if? Would it show up unsuspectedly on random times on their... and where would it appear? In Equestria girls, their cutie marks are shown on their Skirts, phones, laptops, cars and etc. But what if it would appear on your physical body? Is it like a tattoo, or wut. 

So, yeah.. >_> If we had cutie marks, who gave us the cutie marks? o.O if all 7 billion people on the planet has one, the guy who gives the cutie mark must be a creative person. Let me know what you think on the comments. This may be stupid or anything liek that .__. but I'm curious :3
