Easter Finger 

The desired result from inserting a finger into a female vagina durring her minstrel cycle on easter day. The finger(s) should be red and allowed to dry. Authentic Easter Fingers are made using actual female rabbits. The odds of getting an Easter Finger are rare and therefore highly desireable.

Ira got his Easter Finger and red wings on the same day.

finger eater 

Someone who spends a lot of time literally eating the ends of their fingers. Not to be confused with biting nails.

Philip is always biting his finger nails.
He's not biting his finger nails, he's eating the skin off the end of his fingers.
Philip is a dirty finger eater.
