Similar to a volcanic eruption, except erupting out of a vagina. Vagmatic eruptions are different from volcanic eruptions in that they omit 'vagma' instead of magma. The substances are both similar in nature as they both have the ability to destroy small communities and kill everyone within them. Vagmatic eruptions are usually followed by vaginal tremours, and can cause vaginas to "waterfall". Vagmatic eruptions are usually caused by an immaculate display of pimp game by two brofessionals, either on the dancefloor or in similar settings. A brosef must be extremely talented in the pimpage of women to cause a vagmatic eruption.
