Cuck comes from cuckhold...a weak person, generally applies to men on the left. A shill is a person who is covertly posting things for the other side. Some shills are paid by Chy-na and might appear to express concern about issues, but really they are trying to persuade or gaslight people. Shills also come from the left and they post things that are inappropriate that are designed to troll people here. Shills also downvote posts here. Pedes are all of us Trump supporters...comes from the term centipede, a hollow-fanged nimble navigator who is both stealthy and lethal. Karma refers to the upvote posts people get...some shallow, needy people just make accounts and post things to get high karma points...this is especially true on Reddit.
