It's a local branch name of your choosing. If you don't plan to modify
the repository and don't care about then later finding that state again
by its name, you can just check out the fetched commit without giving it
a (branch) name:

git checkout FETCH_HEAD

Branches in git are basically named pointers to specific commits, a lot
like tags are, except that branches follow you around when you add new
commits while they are checked out. If you feel like reading a lot more
about this, have a look at the Git book [1], chapter 3.1 [2].
