At first I could not think up any expressions my parents used a lot when I was a child. Some friends of Ms. Zebra remembered, sweet mom saying often "Jesus, Joseph and Mary". There were a few "wait until your father gets home" and examples of child abuse. That is, "Do I have to get the Board of Education?"; that being a paddle that once had an elastic string and ball attached to it.
A cousin, may he RIP, lived with my grandparents. He told how our grandfather would send him out to get a switch and if the tree branch (maybe the proper word is twig?) was not thick enough or big enough, would send him to get another. Purpose: Charlie was about to get a beating. Several variations on the "somebodies gonna get it now" theme.
As more people post, more memories of expressions return and I am starting to wonder if my parents ever said anything nice to me at all.
