sensu obsceno (sens. obsc.) = with obscene meaning, with an obscene sense, obscene use. Typical abbreviation in older dictionaries for taboo words commonly translated by Latin euphemistic terms like pudenda muliebria. It could refer to a part of the body or a sexual act. In the Greek version you may see it as "ἐπὶ αἰσχρᾶς σημασίας".
