ditch banger
A snowmobile (also see “snow machine”) possessing the appropriate suspension travel and handling characteristics to ride haphazardly, or drunkenly through rural drainage conduits. First coined in the Midwest, it is gaining popularity in mountain western states.
That Polaris with the 12 inch suspension made one hell of a ditch banger until I didn’t see that mailbox and then holy-wah, there it was!
