The girl everyone rode at school. Basically, the easiest girl to get laid with and the one all the boys used for a quick, easy fuck.

An easy lay.

It's been the dream of all high school mountain bike racers, their coaches, parents, and close friends since the start of the first high school mountain bike league in 2000. Now, on June 27th, 2010, NICA (National Interscholastic Cycling Association) transformed from "idea" to legal fact with the filing of numerous forms. NICA is now a central governing organization in high school mountain bike racing in the United States. High School mountain bike racing is now considered an official, national sport.

June 27th, 2010 is the day that high school mountain biking is going to be celebrated by all whose it concerns.
Person 1: National High School Mountain Bike Day?? Mountain biking isn't a real sport!

Person 2: Check it, bro: (brings up CyclingNews.com article about high school mountain bike racing becoming an official sport) and don't hate

Person 1: ...Well, it's still lame.
