A blue waffel is a bruised vagina, in sexual terms.
What Is Blue Waffle Sexually Transmitted Disease?
Any STD can be transmitted via blue waffles. You cook waffles with blue dye, and after you've cooled them, you spread on the STD in the butter. A person who eats this MAY come down with the STD. Who knows? Am I waffling here? Am I blue? I guess I am a blue waffle. Lol
