What is a Zombie? Why are Code Reviewers so violent and talking about killing Zombies all the time? And what ammo are they talking about? What is a TS? What does RSA mean?
And what other Code Review-specific memes are there?
(As the number of memes grows and grows, and Malachi's wish to vote for the memes more than once, this really ought to have its own meta-question)
Please provide only one, or just a few tightly-coupled, memes per answer.
