Well that does it, "Valley Girl" is like so 1980's..Back before Madonna had sex with all the muppets...Hope the OP will tell us what a "black accent" is. Oughta be a hoot.
AOC was speaking like she was a sassy black pastor giving a sermon. Normally her speech is sorta valley girl style littered with "um...like" but this time she's all "ahm PROUD ta be a bartender ain't nuthin wrong with tha"
