mountain bike girl

A girl who puts the fun between her legs. She’s extreme and loves to go fast and give a full send. Mountain bike girls would rather be out riding then stuck in school. They are adventurous, wild, fun. Mountain bike girls are epic and the whole package

Boy “look at her”

Boy 2 “she’s a mountain bike girl”
