NÁ SCOITEAR, a road sign we see in Ireland, which means do not pass, when I was a kid my granny used to say, you little scoitear ya, if we were being a bit bold, "he is a right little scoitear", he is a right little shit. Ná scoitear does mean do not pass, but originally it meant pass bodily fluids. Next time you see it, it literally means DO NOT SHIT. New age Gaeilge, makes me laugh anyway.
@Yvonne this was my father's go-to 'term of endearment' for me.
