One of the members of Chumbawamba is in a band called interrobang or maybe interrorbang so I had heard of it. 6/7, got the Oxford comma one wrong. "Last in a list", like: a,b,c,d, ? Could have phrased it better.
Never heard of them. Do you eat them with your fingers whilst in front of the telly watching River ****ty?
Correct, and they are used like this. *To be honest, I thought the main reason was before the word, "and".
That's the most common usage, yes. They're not proper English, however they are used (by preference) when it makes a sentence more semantically readable. Proper: The guys I hate are Monny, Mindy and Barrie. Oxford: The guys I hate are Monny, Mindy, and Barrie. The Oxford reads better. The Proper reads like two groups (Monny) and (Mindy and Barrie) rather than the intended three. And, as you have rightly noticed, Oxford commas crop up in natural sentences too, despite it not being Proper English. Has anybody noticed that spellcheckers in some apps and applications are actually pushing Oxford commas? It's a ****in conspiracy
