It's right there [in the Meme question][1]. It means just deleting a tag. With fire.

In all seriousness, here's what usually happens:

A tag, when it's burninated, is removed from all questions that carry this tag. 
This will just remove the tag from the system, but it can easily be re-created by users [with the privilege to][3].

If a tag is really bad, and chances are it'll be recreated soon, then it can be blacklisted. Only few tags are blacklisted, but there are many good examples, such as [tag:homework] on Stack Overflow, or the [tag:pc] tag on Super User, which are both [Meta tags][4] and shouldn't exist.

To get a tag blacklisted, asking on the site's Meta is a good choice. This is nothing moderators can do—in fact moderators can't delete tags either—so it'll require community consensus and a developer to do that.
