Latin obscenity is the profane, indecent, or impolite vocabulary of Latin, and its uses. Words deemed obscene were described as obsc(a)ena (obscene, lewd, unfit for public use), or improba (improper, in poor taste, undignified). Documented obscenities occurred rarely in classical Latin literature, limited to certain types of writing such as epigrams, but they are commonly used in the graffiti written on the walls of Pompeii and Herculaneum. Medical, especially veterinary, texts also use certain anatomical words that, outside of their technical context, might have been considered obscene.
