I'm living here for almost a year now and I do understand what it means but I don't.
When someone says "grand" to me I expect to get 1000 euro's or so.. but I never do, but specially in other terms and words why saying "grand".
It's grand = It's okay? or it's great?
Why not use those two.
When I search on Google I get "slang", so I searched what the hell slang is.
And there are two options
attack (someone) using abusive language.a type of language consisting of words and phrases that are regarded as very informal, are more common in speech than writing, and are typically restricted to a particular context or group of people.
Wiki tels me:
https://en.wikipedia.org/wiki/Slang"It's a taboo term in ordinary discourse with people of a higher social status or greater responsibility."On the other hand, slang tends to emphasize social and contextual understanding. The expression "down size" is an example of jargon, while the adjective "gnarly" is an example of slang. "Down size" originated from 1990's era corporate jargon, as a euphemistic way to talk about layoffs.
I never grew up with those words that's why I ask.

Anyway, why the slang instead of proper English?
