Heh.

In seriousness, I don't take typos / slips of the tongue / accidental word substitutions / etc. to be examples of what I'm talking about. As I said in my reply to drethelin, cargo cult language is one cause of word/phrase misuse, not the only use. The cases where someone corrects you, or asks for clarification, and you go "ah yeah, whoops, of course I meant X and not Y", are not cargo cult language, I'd say. I don't take such cases to make a difference to the point, which applies when people are intentionally saying something which has a meaning that they aren't aware of.
