This is a term spoken in the form of a question asking someone if they know what you are talking about. In some cases, ‘Tamn Bout’ may be used as a statement of fact and is particularly fun when understood by another party.
I just got off work after a long day..my back is killing me Tamn Bout? Or (!)
I don't like it. I'm not interested in it. I don't agree with it.
I was so sick last week; I'm not bout it.
Often pronounced like 'Baht'. Bout derived from about, is often used as a contracted version of this. However it is often used as a synonym of without, hence the Yorkshire Anthem, 'Ilkely Moor baht'at'. This use appears to be more common in Northern England.
Used as about: 'Us and lads were out and bout the other night.'
Used as without: 'Our lass was on Ilkey Moor bout a hat.'
