Have you ever wondered where those weird sayings or cliches we use every day come from.
Some of them are as old as the hills, while new words and phrases creep into common speech and become flavour of the month.
New book 'Spilling the Beans on the Cat's Pyjamas' reveals the origins and meanings of some of the most popular and obscure sayings that we use everyday, the Mirror reported.
One of these saying is "Cat got your tongue?" which is a way of asking someone why they are silent.
There are several theories to the origins of this phrase.
Some argue that it stems from Middle Eastern punishment techniques when liars' tongues were ripped out and then fed to the kings' cats, while others suggest it refers to the cat-o-nine-tails that was used to flog sailors and force them into silence.
Another is "flavour of the month." This is an American advertising phrase from the 1940s attempting to persuade shoppers to buy a different flavour of ice cream each month instead of sticking to their usual choice.
