In the urban dictionary, cheese pizza was a way to refer to child porn. Those sickos knew this, but normal people  had no clue. I posted on here awhile ago, that a blog that Va Tech college students used(long since scrubbed) had a conversation going on that friends of the girl and guy who murdered the 13 yr old girl (to see what murdering felt like) were talking about loving cheese pizza. At the time, I had no clue, but since it was weird, it stuck in my head about that. Then, of course, the Wikileaks drop and all the codes...cp being the biggest revelation
