The word fadoodle is slang, and it has at least one fairly direct use as a substitute word for penis. This might allow someone who uses it to avoid using the more "correct" term in public. A couple of other similar uses in sexual banter exist. It appears to be "growing" some other definitions, as slang words often do. If you fadoodle the opponents, it might be said you confused them. Doubtless we'll see more applications in the future if the word catches on and its usage broadens.
