monthly cycle 

Refers to any of the twelve new bikes that every woman in the world receives for free annually, evenly spaced out over the course of the year.

One of the biggest reasons that a guy has such a hard time understanding women is that they are always given twelve free bikes each year, whereas a guy hasta BUY a new bike any time he wants one. (Well, it MUST be true --- gals are always talking about their **monthly cycle**...!!!)

Monthly Duty Cycle 

An absolute lie about how many pages your printer can print in a month. Take this number, divide it by 20, and that's what you can actually print per month without destroying your printer.

Pat: Our new printer has a Monthly Duty Cycle of 300,000 pages!

Pedro: So we can print what, 500 pages a day?
