Down a few too many pints at the pub and you’ll stumble on home looking a bit legless. No, you still have both of your legs; you’re just drunk.

I crawled out of that bar completely legless.

We’ve all seen people leaving legless after a heavy session in the pub.

Got full marks on your math test? You must really know your onions. While it sounds smelly, this phrase actually serves as compliment meaning knowledgeable or clever. It reportedly derives from a man called S.G. Onions who used fake coins to teach children about money. If they picked up the lessons, they would then know their onions, according to BBC.

Similarly, knackered is the colloquial way of saying tired. Example: We bet the Duchess of Cambridge is feeling especially knackered these days with a newborn and two toddlers around.

After working the whole night, I was knackered.
I’m completely knackered after the weekend!

Jet lag got you feeling groggy? You’ll want to head for the kip (your bed) ASAP. You can also use it as a verb meaning to sleep or nap.

Calling something a load of codswallop is the equivalent of dubbing it nonsense. The British tabloids calling out Kate Middleton’s fingers? Codswallop!

Queen Elizabeth II must be quite chuffed, meaning pleased or delighted, about the two royal weddings on the calendar this year: Prince Harry and Meghan Markle on May 19, and then Princess Eugenie and Jack Brooksbank on October 2.

This one’s just fun to say. The sidewalk outside of the Lindo Wing was chockablock — or full — of reporters during the birth of the royal baby.

If you order fish and chips, don’t expect to receive crunchy Lays on the side. In an eternally confusing switcheroo, Brits call French fries “chips” and their potato chips “crisps.”

Cheese the food is great. Cheesed off the feeling? Not so much. This one’s a synonym for annoyed or displeased.
