Sociolect
A sociolect associated with Valley Girls termed “Valspeak” spread across the United States during the 1980s and 1990s, heavily populating high-school teenage female slang throughout. Qualifiers such as “like”, “whatever”, “way”, "as if!", “totally”, and “duh” were interjected in the middle of phrases and sentences as emphasizers. Narrative sentences were often spoken as if questions using a high rising terminal. Heavily accented words were spoken with high variation in pitch combined with very open or nasal vowel sounds.
