A volcano is a powerful and dangerous geological metaphor. Volcano is primarily used to denote functions of humanity, such as catastrophic acne or the unmentionably mentionable experience of male orgasm. Volcanoes in literal form still exist on some planets or exotic moons like Jupiter’s Io, but on New Terra they only exist in the imaginations of children and perhaps some of the more quaint corners of the sphere, like the Pacific Rim. Also, used as a figure of speech, it implies something that is uncomfortably hot, such as in the phrase “It’s hotter than a volcano vagina in here.”
