This might just be a me problem, but I don't like that they use the word toot in Mastodon.
When they chose that word, they probably were going for the sound an elephant makes with its trunk, because a mastodon is similar to an elephant. But I have always been aware that toot is another word for flatulence. So personally it makes me cringe.
You can imagine what it's like for me if you replace "toot" with "fart" on mastodon. Now everyone is talking about liking the best farts, sharing someone's fart, etc. I'm not suggesting they change it on my account, I just wanted to share and see if anyone else had the same problem.
Edit: Apparently they already did change the name
