I'm about 1/4 Irish, so now I should look for clever little Irish/Gaelic sayings:
Go n-ithe an cat thú is go n-ithe an diabhal an cat
May the cat eat you and the devil eat the cat
Aithníonn ciaróg ciaróg eile
A beetle recognizes another beetle
(Similar to the English phrase, "Birds of a feather flock together")
Is minic a bhris béal duine a shrón
Many a time a man's mouth broke his nose
Ná glac pioc comhairle gan comhairle ban
Never take advice without a woman's guidance
And a little more off-color:
tigh na galla = son of a bitch
cacadair = shitebag
fein-riaradair = wanker
Thalla is dean cac mhor bhuidhe!
= away and do a big yellow shite!
Okay, sometime maybe I'll look for sayings from the rest of my boring whitebread ancestry: I did the Irish from the Scots-Irish, but that was Gaelic, and they say there are NO swears in Celtic! The easy one will be French (Actually French-Canadian) "merde!" etc.etc... but, then we've got Swedish and Polish.
........Naahhh. I've lost interest. :\
