This shit drives me up the wall even more than “unalive”
You can’t stop people saying slurs but an entire generation will subconsciously alter their entire vocabulary because they grew up on corporate platforms with very heavily moderated text chats and comment sections and they ended up internalising the filters 
Edit: I was not aware of the AAVE origins of “ahh” which pushes it more towards the territory of legit slang. Still, I stand by my general point about automated moderation influencing language being bad
The other side to this is that ahh for ass is an eye dialect for certain AAVE lects (e.g. in this version of “Crank That” by Soulja Boy, “I’m jockin’ on yo b#### ahh”)
Incidentally, I saw a short by Unsightly Opinions today where she was talking about cutting food as a blind person, but she couldn’t say either “cut” or “knife”, and thus circumlocuted them as “make food smaller” and “implement”. I’m reminded of Oceanian name taboos, except instead being a product of worshiping ancestors it’s a product of worshiping The Algorithm.
