Mine did. When I was about 9 years old. I forget what I said, but it likely wasn’t nice. At any rate, I probably deserved it.
Yeah, once. I was younger than nine. I think it bothered my mom more than it did me.
I got my mouth washed out once. I said “shit” after falling down a flight of wooden stairs. My mother was fond of a terribly harsh old soap called “Fels Naptha” for that purpose. I will say to this day I don’t cuss.
StG
Yeah, she stuck a small piece in my mouth once. I was about 6 probably. Then she gave me a strange look…one I recognize now as the parental “I’m not sure I’m doing the right thing” look.
Didn’t work for me, I still swear like a sailor.
I think my mom used the wrong brand.
My parents never did that I remember, but one of my aunts did. I believe I’d called her a jerk or something like that; I was about four.
I still remember the way it tasted…it was horrible, but not unbearable. It tasted…well, it tasted exactly how you’d expect soap to taste.
I also think it bothered her than it bothered me, though.
yup… actually I got soap twice… then Tide Laundry Soap… and got promised Red Devil Lye if she had to do it again… luckily I didn’t get caught again!
It god damn happened to my ass once and I never fucking swore again.
yes, when I was two I called my 5 year old brother a “big, fat, fuing ahole” 
Not that it was my fault, I wonder where I learned to talk like that?
My Father once was about to do this, until my Mother yelled out “do you know how much that soap costs?”
Nope, but then I was the one who chastised my mom for cursing.
But my Grandmother did use soap to take teeth impressions of my dad and sister and brothers. You know, one of those “Look at how small you were back then” kinda things. Poor guys.
I was like Ralphie in “A Christmas Story.” I was a soap conneseiur. One time, my grandmother even tried slapping my tongue. Imagine the frustration of a 70 year old woman trying to get a grip on the tongue of a six year old boy with just her thumb and forefinger. Didn’t take her long to give up and give me my first taste of Tabasco
Yep, for trying a profane word, back talking and sucking my thumb. It worked on the profanity and back talking but not the thumb sucking.
No… never. My mother wouldn’t… do that… to me. I mean, come on, soap?? She wasn’t a tough mom, I don’t… remember… swearing… ever… hmmm soap… yeaaaaahhh… soap… mmmmm soap (involuntarily starts to salivate ala Homer Simpson) MMMMMM soap… unggggh (tongue out and eyes glazed)…
SOAP…
My mom tried once with liquid dishwashing soap. I snagged the bottle and squeezed it all down the drain before she could do anything. It was rather amusing. I was like 13, though.
Urk! I sassed my mom and she brushed my teeth with soap. The brushing part got the soap distributed into every crevice of my mouth so hours later I would get little zings of soap flavor. I didn’t sass her again till I was twelve-- six years of attitude free parenting for one brushing is a pretty good return.
Yeah. I don’t remember why.
Did you know that toothpaste is just flavored soap???
Try brushing your teeth while driving 20 minutes to the dentist office.
Don’t spit til you get there.
Yes. I think it was Ivory soap. I think it was maybe one, two times. It was in the kitchen that she did it, I remember that. I was probably pretty young–like 8 or so. Don’t remember the reason why, but I doubt it was cussing. I didn’t start cussing until I was older. 
I never had soap used on me because I swore… though once mom accidentally gave me soap because she had stored some green liguid soap in a cough syrup bottle (one of those ones that are colored differently for different flavours) I had to tell her it wasn’t cough syrup and then she freaked out and called the poison center cuz I’d swallowed it (she made me swallow when I tried to spit it out because she thought I was just well… being a kid and spitting out my medicine) She never made the mistake of putting liquid soap in cough syrup bottles again.
One babysitter regularly used tabasco sauce on her own children for sassing her and/or swearing. It never appeared to work on them but she never did it to us (mainly because we were polite to her AND we weren’t her kids)
Another Fels Naptha survivor here.
I was 8 years old and said “G*damn!” because I was locked out of the house. Little did I know that Mom was doing laundry and heard me through the basement window. I can still taste that funky yellow soap.
However, unlike StGermain, I grew up to curse like a sailor.
