[Mastodon]

The new kings of the heavy metal world. They are a prog-sludge metal fusion, with their earlier releases leaning towards sludge metal and their later releases leaning towards a prog-sludge fusion.

Their 2004 albumn Leviathan is a classic record and their 2006 albumn Blood Mountain launched them into the mainstream. They have a new albumn, Crack the Skye, coming out Spring 2009.

All of their albums center around a different element and story 9with the exception of Remission, which loosely focuses on fire). Remission is fire, Leviathan is water, Blood Mountain is earth, and Crack the Skye focuses on aether.

Remission (2002)
Leviathan (2004)
Blood Mountain (2006)
Crack the Skye (2009)

Mastodon are the new knigs of the metal world.

mastodon

mastodon is, besides an extinct mammal and a metal band, a decentralized open-source social media tool. If I'm understanding it correctly, there are a lot of different servers running mastodon software. These are called instances. People with accounts on one instance can interact with people on other instances. All these instances together are called a federation. It seems to be particulary popular with people who are fed up with twitter, because of it's lack of ads and increased discourse between people running the instances and people using it. It also seems to be popular among japanese people, for two of the biggest instances are japanese language, one of which is hosted by pixiv.
It is also possible to host a private mastodon instance that is invisible to outsiders. This could prove very helpful for companies.

Mastodon Tits

MASSIVE tits. Boobs of such grand proportions that they could knock someone out if the women possessing turns around too fast. You can hear the milk swooshing within the tits because there is so much extra space within.

Don't get too close when you surprise her, if she spins too fast and you're within range of the Mastodon Tits, they'll send you to the moon!

Mastodon

A prehistoric elephant that was a close cousin of the elephants and mammoths. It probably fed on leaves from trees and bushes.

I know of the mastodon because of Denali (the mastodon character from the old Gumby cartoons).
