Toots are posts. Boosting is reposting so your followers can see it. Instance owners can change the terms to whatever cutesy terms they want, so this example has boost replaced with boop and toot replace with toot.

Also this is a FINE example of why niche communities need unbiased online infrastructure. A casual google-searcher may judge them by whatever google's AI decides is representative of the group, and choose not to deal with them at all.
