It is when plants have sex like bushes trees flowers. The male plant penetrates the female plant resulting in a big mess...plant sex

When you eat dirt for the first time and leave your family to build a shack in the woods

when you penetrate a living organism of the kind exemplified by trees, shrubs, herbs, grasses, ferns, and mosses, typically growing in a permanent site, absorbing water and inorganic substances through its roots, and synthesizing nutrients in its leaves by photosynthesis using the green pigment chlorophyll with a male erectile organ of copulation by which urine and semen are discharged from the body and that develops from the same embryonic mass of tissue as the clitoris and your penis gets infected and has thorns sticking on to it with it still bleeding but you still keep on penetrating the plant.
