Wardrobe malfunction
Washed up
Water under the bridge
Wear your heart on your sleeve
Well hung
Wet behind the ears
Where there's muck there's brass
Whipper snapper
Whistle and flute
White elephant
Wild and woolly
Wind someone up
Wine and dine
Winter drawers on
Wolf in sheep's clothing
Word for word
Work out
Worse for wear
Would you Adam and Eve it?
Wouldn't be caught dead
