The drops of cum when covering the neck and upper chest area.
The term is derived from the appearance of the male cum, when the male who cums, after being sucked, places his load of cum around the other person's neck. The appearance of the cum drops, resembles the translucent nature of the pearl. Hence its reference.
To ejaculate where the male attempts to aim and place the cum on the other person's neck or upper chest in a string of drops.
