Go wash the wilnots from the baieegs of yer barse
Heard in Waterford
An instruction telling someone to go and cleanse the area between their scrotum / vagina and anus, paying particular attention to remove any balls of cotton/excrement/bumhair.
Why don't you just go and wash the wilnots from the baieegs of yer barse and get out of me face ya cuncha!
Why do you not simply cleanse the accumulated lint from your perineum and remove yourself from my presence, you dreadful miscreant.
