WHAT IS A "SLANG"?
Slang is vocabulary that is used between people who belong to the same social group and who know each other well. Slang is very informal language. It can offend people if it is used about other people or outside a group of people who know each other well. We usually use slang in speaking rather than writing. Slang normally refers to particular words and meanings but can include longer expressions and idioms.
Slang changes quickly, and slang words and expressions can disappear from the language. For these reasons, it is generally best for learners of English to avoid using slang.
Some current examples:
He’s a geek. (someone who is felt to be strange because they spend all their time studying)
Look at those old fogeys on the bench! [teenager speaking about some elderly people in a park]
It’s all gone pear-shaped. (wrong, not as we expected)
Just because American English is so common worldwide does not mean that English speakers of different dialects can’t still confuse one another with slang and local terms. American English speakers and British English speakers both have usages that confuse, and amuse one another. Accents alone can sometimes be enough to form a language barrier, despite the fact that in the U.S., a British accent might be treated as either sexy, or comical depending on the persona it’s attached to.
