The meme can be thoughts, concepts, ideas, theories, opinions, beliefs, practices, habits, songs, or icons. Distortions of corporate logos are also referred to as subvertising. Another definition is: "Intentionally altering a concept or phrase, or using it in a different context, so as to subvert the meaning."
