type (adv) — sense 7

I don't think Brooklyn slang is that different from Manhattan slang. But I'm not used to a lot of the slang my friends use. Months ago, I first heard, "There are mad heads here." I was like, "Where did that come from?" For a while they were saying, "That's type funny." I was like: "What? What do you mean by that?" It means "very funny." Or they were like, "That's dumb stupid." I'm like, "That's redundant."
