Why are they called Pull Requests and not Merge Requests?

Hysterical raisins, as they say. Git was originally created to manage Linux source code. Linux doesn't have centralized repo; it's quite possibly the only project that really makes use of that D in DVCS. Changes were added to mainstream by politely asking the maintainers to download them from you - literally running `git pull` in their repos. A request to pull, if you will. Or a pull request.
