trailaggression
When a trail user refuses to share the trail or berates other trail users who use modes of transportation they don't like verbally or in order to make those users feel unwelcome. Usually associated with hikers complaining about other trail user groups such as mountain bikers or equestrian users or refusing to allow other trail users to pass even when it is safe.
That hiker wouldn't move off the trail so I could pass and when I tried to pass he yelled at me and told me to go ride somewhere else. His trailaggression towards me makes me want to punch him in the throat!
