Though memeticists do not not generally agree on a specific definition, one can roughly define 'meme' as any piece of information transferable from one mind to another. Examples might include thoughts, ideas, theories, practices, habits, songs, dances and moods.

Memes supposedly have, as their fundamental property, evolution via natural selection in a way very similar to Charles Darwin's ideas concerning biological evolution, on the premise that replication, mutation, survival and competition influence them. For example, while one idea may become extinct, others will survive, spread and mutate—for better or worse—through modification. Note an important fact, however: not only the memes most beneficial to their hosts will necessarily survive; rather, memes supposedly spread best by functioning as the most effective replicators, which allows for the possibility that successful memes might prove detrimental to their hosts.
