mountain biker 

Mountain Biker is a shit house person who has OCD. OCD with MTB, shredding, trail cookies, bikes, mahalo, marlo and Whistler. OCD also with kamikaze, such as launching himself off big ass jumps.

Only rides park, dad only comes to witness first-hand where the ambulance will take him to this time.

Mountain biker somehow believes that riding around, shredding trails, forest surfing and eating trail cookies is more beneficial than finishing school. (AKA bro).
Common vocab used by mountain biker is mahalo, marlo, shred, trail cookies, shred hard ma dudes and im faster than you.

A mountain biker is a forest surfer who shreds.

National High School Mountain Bike Day 

June 27th, 2010
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.
