Donutting is the act in which a female punctions a whole through the center of the donut with her partner's shaft and slides the (preferably jelly or cream filled) donut down the penis. She then proceeds to bite the donut til it has been completely consumed. At this point, she licks the rest of the jelly/cream off of the penis.
When my girlfriend donutted me last friday, it felt sooo damn good!
The act of killing an opponent and proceeding to use the 'squat' feature to move up and down on the laying down body of the dead opponent. This resembles the act of moving the anus over a laying persons face.
