Is there a name for this literary pet peeve?

Not nearly as bad as those who use an acronym, maybe even one they have just made up, without ever explaining it, something to which Dopers seem particularly prone. :mad:

Anyone else ever tempted to just throw some random letters in a post to confuse people?

“I went to the movies last night FLL”.

Well that’s different, if you’re going to be mentioning EVOO several times over the course of your post.

But saying WWW instead of worldwide web (in speech, not writing) - now that’s not going to save you any time at all.
