There are some things we are accultured to not say. I don't remember using the compound BS any time before now even though this doesn't mean I can avoid uttering other mean words altogether at all times. It is only human.
The second word in the compound is repulsive or repugnant enough for anyone to refrain from including it in one's lexicon. So, I kept wondering how it comes easy for others to use it in public or privately. I understand it is used metaphorically. Even then ...
Then again, while looking at some data this past Sunday, I couldn't help uttering that it is SS (savage S.) At that moment, I could only realize why people are overpowered at times to utter the compound BS.
