Why here used "is"? Isn't it "are"?

You are right, it should be "are" in this case and this sentence is not grammatically correct. The reason they use "is" in this case is because they are speaking in slang. This is common among many lower class communities in the United States, as people in low class communities generally do not use any formal language and speak informally and non-grammatically.
