Has any of you received an enema, from a parent or caregiver (or... spouse?) for "attitude adjustment"?
By this I mean that the enema giver would decide that, based on your behavior (cranky, obnoxious...) that you needed an enema, without there being a clear sign that you were constipated or had a stomach ache; or that the enema was considered partially a punishment (it was given partially because the enema giver knew you disliked it).
In our couple we sometimes give an enema, often preceded by a spanking, for obnoxiousness - to flush away the bad mood, so to speak.
