A sociolect associated with valley girls termed "Valleyspeak" arose in the San Fernando valley in the 1980s. Qualifiers such as "like", "whatever", "way", "as if!", "super", "totally" and "tubular" (a surfing term) are 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.
The height of the "Valley Girl" period was during 1982-83, with several films, shows and music of the New Wave era embodying the "Valley" atmosphere of the San Fernando Valley during that time.
In 1982, composer Frank Zappa released the single "Valley Girl", with his 14-year-old daughter Moon Unit speaking typical "Valley Girl" phrases. Zappa intended to lampoon the image, but after the song's release there was a significant increase in the "Valspeak" slang usage, whether ironically spoken or not.
The 1982-83 CBS TV show Square Pegs featured Tracy Nelson playing Jennifer DeNuccio, a popular Valley Girl at the high school.
The 1983 film Valley Girl starring Nicolas Cage centered on a group of "Valley Girl" characters and featured several characterizations associated with their lifestyle (such as going shopping at the mall or "Galleria," suntanning at the beach, and going to parties).
YouTube creator Liam Kyle Sullivan's character Kelly, a blonde teenage girl obsessed with fashion and self-image, speaks with an over-the-top Valley Girl inflection.
