My Blue Waffle What Is The Medical Name For "Blue Waffle" And How Do You Get It?

What is the medical name for "Blue Waffle" And how do you get it? - my blue waffle

This is just out of curiosity: Honest Q:)

Basically, my friend plays this trick on me and said that Google "Blue Waffle" and click the first link. (I wouldnt advise this) and I'm curious:)

I asked myself:
1. How do I get / what is the cause?
2. Why is Blue Waffle (I have the little blue, but not waffles)
3. What is the medical term?
4. Is it an STI?

If you can answer all these questions are happpy ID: P
