Homebrew Terminology
Formula: A package definition written in Ruby
Keg: Installation prefix of a formula (e.g., /usr/local/Cellar/pipenv)
Keg-only dependency: Dependency that isn't symlinked to places like /usr/local
Cask: An extension of Homebrew to install MacOS native apps (e.g., Atom and Google Chrome)
Cellar: Where kegs are installed (/usr/local/Cellar)
Bottle: A pre-built keg (rather than one built from source)
Tap: A git repository. To tap a repository is to make a shallow clone of it.
Brew bundle: An extension of Homebrew to describe dependencies

Thanks for this, it's really nice.
I started using homebrew recently, I found out it works on linux too (with some limitations). The output messages and the commands are very user friendly, I like it so far.
