"add to dictionary" abuse
Refers to where you impatiently/imperiously refuse to correct your spelling-mistakes when composing text on on a word-processor, but instead just click "add to dictionary" for each error to make said pesky intervals of squiggly red underlinings disappear.
Not only does "add to dictionary" abuse result in your literary compositions' remaining full of mistakes, but it also potentially harms the next person who attempts to use said word-processor, since your spell-checker will now not "catch" many misspellings that this subsequent typist may make, and thus he may unwittingly not do a proper job of proofreading his letters and memos, either.
