On the Icelandic fediverse/Mastodon I've started seeing people using the word "tútta" for "toot". "tútta" (pronounced toot-ta) is normally a slang term for a boob/tit.

Please reboob this.

@esi So this is completely in line with the etymology of mastodon, from mastos: tútta (það er fyndið)

(Can you tell me if there are a few # that I could use to find islensku túttur? Please 🥺 ) (I really mean toots 😅 )

@HydrePrever i dont know about hashtags but a lot of us Icelanders hang out at the lodfill.is instance.
@esi thanks for the tip!
@HydrePrever No prob. You are more than welcome to follow my Icelandic account at @esi if interested. :)
