chunky susan
When a menstruating female bleeds without using absorbent products (i.e. tampons) or showering for the duration of her cycle, allowing a healthy and substantial menstrual scab to develop. A partner will then chew off the scab, and spit it in to the female's mouth. They then spit the mass back and forth, similar to an egg toss.
Since my favorite prostitute is bleeding from her hatchet gash this week, I am paying extra for a Chunky Susan.
