A form of digital-anal intercourse between men, where a finger is inserted deep enough in the rectum to put pressure on the prostate as an accompaniment to oral or manual sex.

Also sometimes called a "spiff" or a "McSpiffy."
He didn't seem to like the blowjob until I gave him a McSpiff. Now I remember to spiff him every time.
