Discussion Forum—A Way with Words, a fun radio show and podcast about language

Ok, I'm old.....and this must have come from my parents, so maybe none of you "spring chickens" (another ancient expression) is using "scared the peewadlins (sp?) out of me." I'm interested to know if anyone else has heard it, and if you know anything about it. I'm guessing it comes from getting so scared you pee your pants, and maybe someone put in the rest to avoid saying something in front of a child (?)....but have no idea, really.
