From a review of the new book “The Life of Slang”:
“The arguments in favor of slang [are] about slang itself: it is vibrant, creative, and so on,” she writes. “These qualities might be attributed to slang-creators. The arguments against [are] largely about slang-users: they’re unintelligent and have limited vocabularies. And that’s one of the reasons why I find it hard to take sides in this argument: slang words often are witty and appealing, but not all slang-users are. On the other hand, slang-users might be perfectly charming were it not for their irritating repetition of tired slang words. …
What really sets slang apart from Standard English is the way it functions in social contexts: communicating meaning is often a secondary function for slang; it’s really for communicating attitudes and cementing relationships.”
Slang “creates in-groups and out-groups and acts as an emblem of belonging.” To Coleman, “the importance of slang in creating and maintaining a sense of group or personal identity” is paramount, and all the evidence supports her. Groups that have developed slang as a way of cementing their identity include the military, especially in the lower ranks. …
In sum, according to Coleman, “slang is an attitude (insolence, for example, coolness, disdain, admiration, or a desire for conformity) expressed in words.” … “Slang was once considered a sign of poor breeding or poor taste,” Coleman writes, “but now it indicates that the speaker is fun-loving, youthful, and in touch with the latest trends.” (more)
I suppose this helps explains why I’m not into slang. I want to talk to the widest possible audience, and to focus on timeless issues and insights, as opposed to the latest fashionable topics. I can see why people want to signal loyalty to their groups, especially in the military, but I have little confidence that this is good for the world as a whole.
While I have fun talking the way I do, that isn’t really what people mean by “fun-loving, youthful” – they mean more that if you were young you’d be sending the right signals about your being a good person for others to have fun with. You’d be a good person for the typical young person to have as a friend, associate, or lover. And that, I’m not.
You sometimes use odd abbreviations which some might call slang, e.g. "tech" or "ems" - I recommend against using them.
Yes. "Em" and "Ems" I tried wikipedia and couldn't figure out which one. Tried "em scenario" on google, not luck. I'd say that's slang/jargon.
