In William Shakespeare’s time, the word “nothing” was slang for vagina.
The reason for this strange nickname is because this part of the female sexual organ is round like a zero (0). Other fun Elizabethan terms included: “thing” for penis, “merry” when someone was sexually aroused, and “country matters,” which referred to matters pertaining to a women’s genitals. Something that the unacquainted may miss about Shakespeare is that his plays were often full of dirty jokes, using now-outdated slang, or simply jump making up his own words. The folks at Cracked have even suggested that he would make a great Cracked writer if he were alive today.
