Colloquialism originated in inner city Dublin, Ireland.
Derived from 'and anyway'. Typically used in phrases where the 'and' is extraneous, the word 'anyway' alone being sufficient.
Often used in conjunction with the word 'buh' (local pronunciation of 'but') as an ending to a phrase.
The word 'buh' is generally used in place of 'though'
