A sex move where the recipient female is being intercoursed from the rear, in the canine style, and just before her partner ejaculates, he pulls an ass cheek to the side so as to expose her butthole, and using the other hand, gives the female's butthole a hard, swift, open palm slap in a smooth, downward motion, so as to cause a warm, stinging sensation. At this point, the male partner ejaculates onto the freshly slapped butthole, thereby "glazing the donut."

(noun) A successful type of theft which results in an acceptable, impressive and rewarding payday for the protagonist.
