What does "meme" mean in the Rimworld? I keep seeing references but have no idea what that means.

[The Blind One]

memes are a term used to denote ideological themes such as nudism, cannibalism, high life, transhumanism, etc which form the basis of the ideoligion of ones colony. They are the building blocks of your colonies culture and religion.

If you don't want to click whatamidoing's link:

A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme. A meme acts as a unit for carrying cultural ideas, symbols, or practices, that can be transmitted from one mind to another through writing, speech, gestures, rituals, or other imitable phenomena with a mimicked theme. Supporters of the concept regard memes as cultural analogues to genes in that they self-replicate, mutate, and respond to selective pressures.

Thank you for all the helpful replies! I understand now that a meme is not necessarily an Internet meme but is used to convey a concept of an idea or culture.

Great answers all of them!
