When someone has some tasty food that they have left unguarded you eat it without the owner permission. Its utterance renders the act more socially acceptable.
"Danger-munch!" *eat slice of tasty pizza*

"Man that was my last slice."
"Yeahhh mate danger-munchh!"

"Did you just eat that last biscuit?"
"Yeahh sorry mate Danger-munch."

"Mate I can't believe that b*****d ate my pizza!"
"To be fair mate, he did call Danger-munch"
