DRY - Don't Rrepeat Yourself is a software development principle which states that duplication of code should be close to zero. And the abbreviation WET - We Enjoy Typing is the opposite of DRY principle.
I was helping a colleague of mine to do a rebase with git and after typing
git st third time he told me
st is not a git command, why are you typing it again and again. I replied to him it's just a habit but on my computer, it's a valid command.
