Look - I've no idea. We were learning to write 'lede' paragraphs for newspaper articles and this popped up. 'Did you copy and paste that?' I said.
'I think you did. What does promiscuous mean?'
'So you copy and pasted, right?'
'Whur', by the way, seems to be a special word for 'I don't know and don't care'. It's banned in my classroom. Despite this, it finds its way into many a conversation.
