The act of penetrating an uncertain
hole. An often risky maneuver, "Splitting the
Casper" involves taking aim in the general vicinity of two known holes, where the entire area is occluded, or glazed-over, leaving neither

Tom didn't care where he ended up so he closed his eyes and "Split the
Casper." Unfortunately for Michelle, he was hitting the trailer this
time.
