No, it’s not a dig at ABDLs, and I would guess they’re not even ABDL-aware. There was commercial that accompanied the listing where it talked about not wanting to go to the bathroom in music venues, which for the vast majority of venues I’ve been to is very accurate. Probably came from hearing about Taylor Swift fans saying they wore diapers at her last tour, but then they wanted to make it “metal.”
So I take it you don’t buy any drinks that are in cans? Because all soda, beer, etc., cans have a plastic liner in them.
