of animals: thrusting one's snout into a camera's lens when your photograph is taken, resulting in a fish-eye view where the nose appears disproportionately large.
The photographers who encourage this are known as orkers. Most notably: Cow Orkers, given cows' propensity to enable this.
Also: puppy orking, cat orking.
Awww this orking kitten picture is soooo cute!
