Originally a nickname given to
British sailors who sailed across the Atlantic and sucked on limes to keep scurvy away.
It is now often used by Americans in two scenarios
1.) When referring to a British person, possibly in a form of endearment.
2.) Referring to 'British
stereotype' (usually in an insulting way) but the insult is not specifically reserved for the British.
Ex:
"Met a limey at the airport today."
Person 1: The people down south are so uneducated.
Person
2: Oh shut it, you're starting to sound like a limey.
"Met a British person today who was acting like a real limey."
Person 1: Here's a picture of me before I got braces.
Person 2: Oh
wow, you look just like a limey!
Person 1: I prefer
tea over
coffee.
Person 2: Oh no, you're turning into a limey.
"You limeys are too polite!"
