Interesting dilemmas when colloquialisms/semantics come into play.
There are 'languages' in certain cultures that don't make sense to folks not acquainted with that culture, making discussions confusing.
I'd just ask, 'I'm not familiar with that term, can you tell me what is a 'stag'. Might have to help with descriptors...'is it a male chicken under a year old?'
