Jargon you use to express having seen or read something that’s so good or so funny, it’s awesomeness has (figuratively) killed you with joy. For example, "Did you see Pineapple Express dude?" "Dead."

That’s all you need to say. Not “I’m dead.” Just “dead.” Your millennial friends will know what you mean.
