Any form of punishment - used in conjunction with spanking - can be a part of any punishment process.
I have shown corner time, enemas and other forms of associated discipline - but one that goes back to early childhood - and effective even for adults is soap in the mouth.
Here a mom takes her married daughter to the bathroom for soap, because she used bad language. After having the soap in her mouth, and a few reminder swats, the soap is allowed to come out - and then the required apology to her sister for using bad language.
What other punishments have you had? Even as adults?
Havenโt seen a lot of videos featuring mouth soaping.
