I've known about it since I read this tweet

Wait, what?

sinnoh is my favorite region and i didn't even know this. I'm genuinely mad now.

I learned this when I was today years old.

I'm relatively sure ur taking the piss but uh, for reference "The "Down" refers to the down feathers of a bird, the undercoat of feathers beneath the visible layer on top." The fluffier, softer feathers used to fill pillows and duvets and stuff.

@TurboSloth14 used a better word, a comforter would be more commonly used today. Like a puffy blanket, uhh these things.

It took me until last year to realise it

I spent 22 years of my life not getting that word play. I'm retarded.
