Cheekface

One of my favorite bands sings with prominent features of West Coast English. In this song especially, in order to poke fun at a certain kind of west-coaster, the singer's vowels are very fronted. There's also a notable drawn-out "r" sound in "smarter" and "more". The way he says "American imperialism" is especially hilarious.

Bowl cut maintenance 1000

This is a famous video of a man maintaining his bowl cut. As far as I know he did this without it being meant to be funny, but after becoming popular for having such a strong accent, created his merch etc. He is from southern California and obviously uses variables that people associate with California. See: "deuuud" instead of "dude" etc.

Ed Sheeran tries American Accents

In this video, British singer Ed Sheeran is asked by a fan during a Q&A session to do his best "American Accent". He goes on to say that he can do three different ones, starting with the "Valley Girl from California" one, then moving to the "Regular" one and ending with the "Southern Draw" one. Since English is obviously one language in and of itself, but different English speaking countries have different accents. For example, Ed has a British English accent. But there are also Australian English accents, Irish English accents, and so on. There are different accents for different parts of the world, but there are also sub-accents in different parts of the same country, as shown here by Mr. Sheeran.

This is an example of a speech community. In the video, she is referring to the different ways in which her speech community interacts compared to the area she is in now. Her examples should be relatable to many living on the West Coast.
