pup's the word

Da Englishman's term for freely "spilling da beans" regarding sensitive information.

I respect dudes and chicks equally, so I don't even touch da gender-inflammatory subject of which half of da human race is better at "remaining hush-hush". So to me, saying, "Pup's the word" is an insult to guys, as if they are less able to keep secrets than ladies --- whether they've had children or not --- are.
