What the other guy said. This is definitely a common phrase with AAVE, thus, asking the question, “do people really talk like this”, would imply that the asker is considering the poster to be inferior in some way. The racist piece being that it’s pinpointing a dialect spoken, typically, by a specific race and calling it dumb.

I was sort of being sarcastic but lemmy users are a special sort and definitely can’t read that.
