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
So there are places in the US where people pronounce ass like arse
I presume so. I've never heard the full word pronounciation, but I've definitely heard it with the dropped consonant, so I presume anyone in the region who says it with the consonant pronounce it that way. I'm actually lowkey losing it because I have no idea how I've heard one without the other...
