I'm Lilo and I come from the Netherlands. This year I started my English teacher training course. For one of my subjects, I have to give a presentation about slang. My particular part of the presentation is why and when people use slang.
Could somebody maybe help me out a bit? What are the most common reasons people use slang? I've got 3 reasons till now: To sound cool, to speak a language parents don't understand, and because it's easier now we daily use the Internet. Are there any more important reasons for using slang or are these really the most important ones?
I hope someone could help me out a bit, thanks.
