I thought it might be fun to blog a little about the common phrases one hears in AT circles (AT as in Appalachian Trail). I am including an unofficial official glossary of the more frequent terms or phrases you'll hear said on the trail, in a hostel or shelter area, or even online in hiker forums.
2,000 Miler - one who has hiked the entire length of the AT , no matter how long it takes
AT - Appalachian Trail
ATC - Appalachian Trail Conservancy which oversees the entire AT and also serves to educate and inspire

Blowdown - tree or other large debris that has fallen across the trail
Blue Blazing - taking side trails or walking the road other than hiking on the AT
Flip flop - a hiker that starts at Harper's Ferry and hikes to Katahdin, returns to Harper's Ferry and hikes to Springer. Can be done the opposite way also or at a different starting points.
