Any person whose life is defined by outdoor activities such as backpacking or camping. They often sport goatees, flannel, shirts and sandals, and embrace environmental activism. The term is derived from the root "gorp", the mix of nuts, grains, and dried fruits popularly brought along as victuals on the trail.
We could tell they weren't just tourists because their long hair, slender bodies and "GORE 2000" t-shirts identified them as gorpers who'd been on the trail for a while.
