An unofficial day held every year on the second Friday of October (coincides with World Egg Day yearly). Typically falls around the 11th to the 14th of October depending on how the day falls.
The day began as a joke from online sex roleplay chatrooms but has gained some mainstream attention elsewhere online.
Free use means that a couple must engage in sex whenever one of the members of the couple wants to have sex, even if the other member is not
horny. In free use, as
long as one member is
horny, the couple is required to have some kind of sexy
time.
