Meme: Don't roll your own. (AKA: The first rule of cryptography.)

Originator: Unknown. One of the most infamous uses on IT Security is by D.W., here. This meme is also related to / a synonym of "Don't be a Dave!"

Cultural Height: TBD

Background: Everyone seems to want to write their own ciphers, or create their own security mechanisms. Unfortunately, this usually doesn't end well. As such, the phrase "don't roll your own" has become a frequent staple of IT Security advice, as well as on other boards (e.g. Crypto SE) and across the entire information security community.
