Two years back I was Riding down Highway 6 on my 2009 Yamaha R1 (R.I.P.)
and a minivan crossed traffic and hit me, 30 broken bones, 2 months in the hospital and 2 months in out patent therapy and a lot of metal running through both arms, but the name on here comes from the fact that where the gas tank sits on a sport bike is not the best position for a head on wreck. When you hit something head on at high speeds you go straight forward and your pelvis goes straight into the tank. Needles to say I ended up half the man I used to be after this wreck and my buddies started calling me halfsack
after that it just stuck.
