Is there a character for the "current branch" in git?

Question

I need to re-specify the name of the current branch.

Examples

Updating my current branch with changes from remote

git pull origin mySuperLongComplicatedBranchName

Click my current branch to remote

git push origin mySuperLongComplicatedBranchName

---

I would simplify this to a simple one:

git pull origin *

or something similar. If perhaps something like this already exists. I'm pretty used to git, but just hope that I'm missing something simple.

EDIT:

Adding additional information in response to one comment:

git show-ref -head

eaadd6401c4e179c105ac3565fe9bf53e2882f83 HEAD 
eaadd6401c4e179c105ac3565fe9bf53e2882f83 refs/heads/myReallyLongBranchName
d6af452b1ad0a309a55061f9eeb6ab7ae83b6aef refs/remotes/origin/HEAD
eaadd6401c4e179c105ac3565fe9bf53e2882f83 refs/remotes/origin/myReallyLongBranchName`

so it looks like my remote reallyLongBranch looks identical to the current head. Oh, I know. I will

git fetch

then i ran

git show-ref --head again

bc1b96345913e911d03eb62763f8795cc20ecd8f refs/remotes/origin/myReallyLongBranchName

Oh great. Now I have to do it git pull origin HEAD.

I am running a team. and I get Already up to date.

Then I run:

git pull origin mySuperLongComplicatedBranchName

I am discarding the changes. Front palm.
