 KNICKER -CELLARAGE or CARNAL  CUPBOARD :  a lady's traditional log -storage area, source  of creation and centre of pleasure .
From HENRY IV Parts  1 & 2, the complete , unabridged  edition, by William Shakespeare :
" Faroukh me! " quoth Mistress Quickly, hastily hoisting her skirts and beckoning to her favourite knight who, having unfastened his codpiece , was now SHAKING his massive SPEAR  suggestively. "O, faithful Falstaff, pray furnish mine PANTRY with thy sturdy staff , forthwith !"
The hospitable inn proprietrix was indicating the entrance to an ample , thatched property , which Falstaff's friend Pistol had recently poked , which before had swiftly melted the bold Bardolph's iron-bar, but which yet awaited the thrust  of Prince Hal's majestic  halberd .
While her restless hands stiffened the cockney statuary atop her formidable Canary Wharf, the insatiable Quickly continued her appeal:  "Prithee, my gentle Sir Jack: fail me not in my hour of need , but wend your way to Wimborne  with all due despatch, then chew on my chapel peg till I be totally chaucered !"
