Million Dollar Trivia Question

Alright, when you use an eraser on the back of a pencil to erase something, it leaves little thingies behind which you are required to remove by either wiping off, shaking the paper or blowing on the paper.

What the heck are the little remants called? I’ve tried eraser dust, eraser shaving, eraser residue…eraser remnants and none of them appear to be correct.
