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. The entire history of the tag is wiped out, with no trace of the tag existing in revision histories. 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](https://meta.stackexchange.com/questions/295148/what-is-a-blacklisted-tag). 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.
