Massachusettes Mailbag 

A sexual act in which 200 men form a circle around a woman, coming into a mailbag one at a time until the bag is filled with the sperm of every man. The woman in the center of the circle is then hit in the face repeatedly with the bag.

An alternate form of this act is called the Massachusettes Mailbag "Charleston Chew," in which the man who hits the woman with the bag proceedes to shit into the woman's mouth.

Henry wondered why Sally wasn't at work, but then he remembered that she was still recovering from that crazy Massachusettes Mailbag on Sunday.
