scots-irish 

The first rednecks to America, creaters of North Carolina, and some of the most ill-tempered people one has ever met. They are not really Irish, but moved to Ireland for a short time before moving to America, so basically they are rejected Scottish people. Not really some people to be messed with in general.

John: Wow that guy is a real Scots-Irishman
Bob: Yeah, he is a real redneck.

Scot-Irish Agreement

The agreement between a Scottish person and an Irish person that, to avoid a drunken bar fight, neither shall speak or interact beyond greetings and farewells.
This can be sidestepped under rare circumstances, or depending on the levels of intoxication.

Aye, Lance, Ye cannae talk to that boy o'er there.
Why not Pa?
It's the Scot-Irish Agreement, you'd not fancy a bottle gettin' smashed upside y'er head aye?
