Alias "vasta" and "vihta"

I have had two sauna images with one in them.
It was deleted from previous >>2411822 probably because the user didn’t know what the word is and would have been the only image with it.
This is still a topic that Finnish people have not resolved which would be correct term for the bundle of birch branches used to hit oneself or others in sauna for pleasure. This is not lewd in nature.
There is 8 images with tag vihta in it now, but they could also be vasta depending who you ask from.
One of the reasons both could be used comes from the regional differences of origins and language.

Perhaps, to avoid favoring one term or the other, and because Derpibooru is primarily an English-language site (although I’m not sure that’s officially stated anywhere), both tags should be aliased to bath broom (Wikipedia)?

This is true. Derpi is English site.
The problem comes when sauna and it’s culture is not English to begin with.
Sauna and the culture around it is from Finland. Hence why the the terms “vasta”/“vihta” would be better.
Even if not, it could also be “bath whisk” in stead of your “bath broom”

adding image of vasta to quickly referenced

I’d lean toward bath broom myself at the moment, though only really because there’s a wikipedia entry which would make it easier for people to search what it is.
