Warning: Gross - Alternate term for fly guts

Anne and I are talking about flies. There is a huge one on the window screen. I said, "Smash that fly with your finger."

She replied, "Ew! No!"

I said, "Why?"

Anne: "Because sometimes they have boogers come out of their bottoms."

Lydia: "When did you see one with boogers coming out of its bottom? Was it dead?"

Anne: "Yes, I killed it, then I touched it, then I got booger poop on my finger."
