This wont be as exciting if you live in England.
Sorry if this is terrible or inaccurate or there's more than one correct answer but I'm not British so...
.Dessert, Pudding and Last Course are all words used.
.The Tube is just one train, Metro or Trains are more commonly used.
.Upset and Gutted is fine, but Upset is used more often.
.All four is used and again Stupid is more commonly used.
I'm British...Here are the actual answers:
.Biscuit and Cookies are different things.
.Insane, Bonkers and Crazy are words used, but certainly not Radge.
.For Desire, everything is suitable.
.If it's men's underwear, it's Underwear and if it's female's, it's Pants.
.Moron, Plonker and Idiot are words used.
.It's Pharmacy, not Chemist. A Chemist is a person who works there.
.For Awesome, it is just Awesome. Ace is number one and no one really uses it.
.Path and Pavement are both suitable.

Having been to London, I can say that there is more than one word in some of these categories that they use.
