Verbal Backspace

Comedy trope: Alice says something. Then Bob says something or something happens that makes it clear that what she just said doesn't make sense. Alice quickly revises her statement and repeats it. On Second Thought is a more specific case of this, as are some forms of Inflationary Dialogue.

Alternatively, Alice attempts an compliment or insult. However, Bob responds with information contradicting what they thought, which could include Compliment Backfire or Insult Backfire. So, Alice tries again with a new insult or compliment, directly opposed to what they had just said. Could be compounded by a Hair Trigger Temper.

Students of rhetoric may describe this as "epanorthosis". If Alice has to retract a practical idea that uses bad methods, it's a case of And That Would Be Wrong. If she has to retract a controversial opinion, it's a case of Not That There's Anything Wrong With That. If she's retracting an insult to someone she hadn't meant to insult, it's because of Insult Friendly Fire.

The only aim of any and every McCain business is to downsize and halve the quality, to make enough money to acquire another business to downsize and halve the quality, to make enough money to acquire another business to downsize, etc., etc., without ever running a single one of them really well. And if anyone ever raises the question of quality, they're immediately attacked as an elitist, because at Octopus it's considered morally offensive to talk about anything but money. All so that Mr. Rod McCain can feel a little more powerful every day. That's why, instead of running this wonderful zoo properly, we've got to spoil it in order to finance his next mindless acquisition.

 * Online, there are two additional methods to invoke this: striking out the text writing the text in a strikethrough font, and writing one thing and then "backspacing" over it with control-H, written ^H. (Each control-H deletes one letter^H^H^H^H^H^H^H character.) This is a reference to 1980s-era Unix systems, where misconfigured terminals would display control codes instead of invoking them. (A more obscure option is control-W, which deletes entire words ^W^W^W deleted one word in the Berkeley UNIX and in the vi text editor, and was therefore used for more succinct Verbal Backspaces.)
 * Lojban has actual words for this: The words "si", "sa" and "su", to be specific.
