Girl #2: No way, she's such a friggin' TMIF. Last week she spent an hour telling me what douching was like!
Girl #1: Ew.
Thank Mayans it's Friday.
History: The Mayans of Central America relied on not only the sun and moon, but also the planet Venus, to establish 260-day and 365-day calendars. This culture flourished from around 2000 B.C. until about 1500 A.D. They left celestial-cycle records indicating their belief that the creation of the world occurred in 3113 B.C. Their calendars later became portions of the great Aztec calendar stones. Other civilizations, including the modern West, have adopted a 365-day solar calendar with a leap year occurring every fourth year.
Girl : TGIF...THANK GOD IT'S FRIDAY!!
Other girl: No, no...You should actually be thanking the Mayans!! TMIF!
