Me personally? I’ve become much less tolerant of sexist humor. Back in the day, cracking a joke at women’s expense was pretty common when I was a teen. As I’ve matured and become aware to the horrific extent of toxicity and bigotry pervading all tiers of our individualistic society, I’ve come to see how exclusionarly and objectifying that sort of ‘humor’ really is, and I regret it deeply.
This is kind of my point - the majority population never has any reason to think about the origin or evolution of our synonyms for bad, we just pick them up from usage - usage by older people who may have racist or xenophobic intent, or may have picked the terms up by osmosis themselves. That’s how the slurs get engrained in language. But I’m willing to bet, even if you don’t actively think of ‘sucks’ as connected to fellatio, that you’ve used ‘sucks dick’ or ‘sucks balls’ as an emphatic. (If your emphatic is ‘sucks eggs,’ then you’re even older than I imagine, and please forgive my ageism ;) )
Oh then I misunderstood what you meant by your original comment. Thanks for making me think about it, I never really thought about some of the origins of our seemingly mundane slang.
