half Spock

Fingering your girlfriend in both holes, using the index and middle finger. A full Spock would be using your index and middle fingers in one hole, and the ring and little finger in the other.

My lady wasn't satisfied with only a half Spock, so I had to add more fingers.

halfstock

semi-erect or semi-flacid. However you want to look at it... I choose semi-erect, as that seems more positive.

"Man, I'd fuck that shit out of that bitch, but I'm halfstock."
