WET is an acronym for Write Everything Twice (or Thrice) or We Enjoy Typing, where formats or architectures encourage the duplication (triplication etc) of information, introducing increasing likelihood of inconsistencies, like in sidefiles and meta tags like OGP or Twitter Cards. WET is the opposite of DRY.

Another humorous take on WET is the acronym TRY, meaning Try Repeating Yourself.
