Mastodon seriously needs a rebrand.
I think it would be pretty darn easy to maintain a rebranded fork, though.
More seriously, the American Heritage Dictionary gives the following definition:
v.
To sound a horn or whistle in short blasts.
v.
To make the sound of a horn or whistle blown in short blasts or a sound resembling it.
v.
Slang To snort cocaine.
None of which is to fart. I do wonder if that meaning is a regionalism?
