ahahahaha - I found an anecdote about irish insults in the 2013 Boston mayoral race, where the winner of modest background was referred to as "Shanty irish"
and the loser who happened to be wealthy, as "lace curtain" or "two toilet"
"OH AYE, LOOKIT THERE, IT"S TWO TOILET JOHN! Thinkin' he's better'n' us!"
