Drinking is part of Irish history and society. The English phrase 'team drink' becomes the Irish phrase 'deoch fhoireann' when translated.

'Thank you' is an English phrase and therefore has no meaning in Irish.
This (is) he/it.
The phrase 'sky blue' would be 'spéirghorm' in Irish.

As I understand it, and strictly from the folk tradition among the Irish, the phrase refers to the Irishman's quick temper and his inclination to challenge anything that he considers a slight or a violation of his rights. We Irish are supposed to have a quick temper and be ready to fight at the drop of a disparaging phrase. "That comments got his Irish up and his dukes came up with it."
