A biker is a man who rides an american made cruiser most likely the kind of HARLEY DAVIDSONS but not limited to amercian made cruisers although owning a cruiser is a must in order to fit into the biker catagorie. A biker dosent just take his bike out on the weekends but he rides on all night and day whenever his free time permits and often pulls off to the side of the road to nap for a few hours from riding so much and in order to sober up just a little bit . A biker will then wake up and smoke a bowl of some medical and drink out of his flask of 151 and continue on untill work needs to be done or his lady needs to be done , one or the other will get the true biker back to home base . The biker spends every sunday not at church but on his sidewalk in front of his home washing and waxing his bike and saying sweet things to here while drinking a 40 oz of some kind beer and upon end takes off and rides into the sunset not to be seen untill morning sometime . His hair can be long and the biker doesnt care about showers , cologne , nice clothes , or any other sissy boy shit that most proper office working pussys care about and simply he just wants to be one with his bike and second his girly . A biker will be quick to fight you no matter if he gets his ass beat or not and is not afraid of spending a few nights in jail . The true biker loves his momma , hates his daddy , doesnt know if god exists , and believes in no life after death . Although fierce and full of rage for the most part dont take him for being a bad human being because a true biker cares about women and children and will go out of his way to help them anytime of day and will even help out his fellow man if possible . Just dont mistake kindness for weakness and the biker will always be on your side .
Getting shit faced and putting on my mc vest , firing up the davy and going for full night rides is the best thing in life . The sound of the 96 ci motor on the dyna in the silent night on a lonely desert road makes me feel like theres someone else there with me to listen to all the shit ive got to tell it . and i do .Biker for life baby .

Man who eats, breathes and sleeps Harley Davidson. Doesn't own a cage, only owns his Harley. One not to be messed with. Answers to nobody but himself. They make the best friends. Bikers say what they mean and mean what they say. Very large balls. Real bikers ride Harley Davidson motorcycles.
He's a biker and belongs to a MC. Cops are afraid of bikers when they don't have their guns and badges. Bikers are quality people. He's not a biker, he rides a rice rocket. A lot of wannabe's think that they're real bikers. Bikers have no fear!
