Bob’s your uncle

When you hear someone say this, things are effortlessly falling into place. It’s akin to saying, “There you have it.” Its mysterious origins trace back to the appointment of Prime Minister Arthur Balfour, appointed by his uncle, Lord Salisbury (Robert Gascoyne-Cecil).

It’s raining cats and dogs

Chuffed to bits

When you’re overjoyed or delighted, you’ll proudly say you’re “chuffed to bits.” “Chuffed” alone denotes being pleased, but when you add “to bits,” you’re emphasising the depth of your emotion.

That idiom conveys that the mentioned event or circumstance will never occur, implying that it is highly unlikely or utterly impossible. It is a colourful and humorous way to dismiss an unlikely scenario or promise.

Commonly referring to the number 13 instead of the standard 12, this term dates back to medieval times when bakers added an extra loaf to ensure fair trade and avoid penalties for underweight products.

To have a chinwag

If someone invites you for a “chinwag,” they simply suggest a chat or a conversation. This term is believed to have its roots in the late 19th century, combining “chin” (referring to speaking) and “wag” (to move or chat).

Turn a blind eye

When someone consciously chooses to ignore or overlook something, they’re said to “turn a blind eye.” The phrase’s origin traces back to the legendary naval hero Admiral Horatio Nelson, who allegedly turned a blind eye to a signal requesting his withdrawal during a fierce battle.

Bite the bullet

This idiom signifies facing and enduring a challenging or painful situation with courage. Its origins can be traced to battlefield medicine when soldiers would bite on a bullet to endure pain during surgical procedures without anaesthesia.

Brass monkeys

When it’s “brass monkeys” outside, it means that the weather is intensely cold. The picturesque expression “cold enough to freeze the balls off a brass monkey” alludes to the brass rings used to stack cannonballs aboard ships, which shrank and fell off in extremely cold temperatures.
