greentard

Someone who does everything, including the irrational, to be environmentally friendly. Like burning books so they don't need to cut down more trees. Walking across a forest to work so they don't need to use a car, and killing a squirrel's habitat in the process. And buying their anti-car protest placards from Wal-Mart, then drinking a Starbuck's coffee with totally unfair trade coffee shipped in diesel oil tankers 90000 miles to their little town, and then slapped with a made-in-china "fair trade" sticker so they think they're helping the environment.

Sara worked 30 hours at Mcdonald's last week so she could buy an enviro-friendly handbag from Wal-Mart! What a greentard!
