piddly diddly department 

1. The act of urination.
2. The lavatory.

Ooer, I really must use the damned piddly diddly department before I soil my underknickers.

piddly-diddly department 

Somewhere where one goes to 'relieve themself' as oppose to the 'poo-parlour division'!

Random person 1: "I really need to go to the piddly-diddly department"
Random person 2: " Ahem...I think you should have gone to the poo parlour division"

Piddly Diddle Department 

Quite frankly, the bathroom. In a store, you you were peeing, you'd be making the noise "piddly diddly piddly diddly" in your favourite department.

"Excuse me, I must go to the Piddly Diddle Department to rid my bladder of its toxins"
