Some one who chooses not to acknowledge the obvious chemtrails in the sky are chemtards. These people are the stupidest of all primordial scum-bag primates, who for some reason or another, call themselves human. These people are usually liberal in nature, anti-constitutionalist, pro abortion, pro gay, anti gun cry baby bastards who if they live in the US aren't American at all. These people have shit for brains because they refuse to see with their own eyes the chemtrails in the skies above them, hence they're retarded, hence they are chemtards. This was the original meaning of the phrase, not the other way around.
Adrian: Hey Bob, you see all those chemtrails up their in the sky?
Bob: yeah but they're water vapour contrails.
Adrian: Oh Bob, you truly are a chemtard, dipshit moron you know that?!
Derisive term for someone who believes in the Chemtrail Conspiracy Theory. The original meaning was directed at people who are poor at chemistry. The Chemtrail Conspiracy Theory holds that government planes are either seeding clouds to counter global warming or spraying mind-altering or health-altering chemical substances on unsuspecting populations around the world. Chemtards believe plane contrails (condensation ice crystal trails) are actually "chemtrails" (chemical trails), hence the name.
Chemtards are predominantly American, white, racist, scientifically illiterate defeated Republicans who hold President Obama responsible for applying the directives of the New World Order. They also believe in Planet Nibiru.
A chemtard is someone who chose to take chemistry and then realised it was a grave mistake.. and are pretty much a failure in the subject.
