I'll call Anderson 

A sarcastic phrase much like "big deal", when someone announces something mundane and unimportant as if it were important, and the speaker wants to ridicule that with irony. The implication is that what he/she has said is so profound that the speaker will run to the phone to tell CNN anchor, Anderson Cooper, so that the news can be broadcast nationally. Also similar to TMI. A sarcastic and backwards way of saying that nobody cares to hear it.

A: I think I'm gonna go take a dump
