pack sniffer
A smelly, out-of-shape fake who thinks they're one of the cool kids because they know the words to a hiking song, even though they can't walk a mile without wheezing.
@trailbros4ever is just a pack sniffer who uses a GPS to find the trail.
I saw him at the trailhead. He had a map, but it was for the mall.
He posted a video of a squirrel and called it a 'hiker's paradise.'
