Vulgarisms

crude words that are unacceptable in standard speech or expressions that are incorrect in form.

Vulgarisms are sometimes introduced into the speech of characters of the text of a literary work as an intentional stylistic element in order to convey a certain everyday coloration—for example, “Akh, vam ne khotitsia l’ pod ruchku proitit’sia?” “Moi milyi! Konechno! Khotitsia, khotitsia” (“Ya wanna go for a walk?” “Sure I wanna”; E. Bagritskii). In present-day stylistics the term “popular speech” is used more often than the term “vulgarisms.”
