a wrong argument wearing a tuxedo, confident enough to fool the room.

means A flaw in reasoning that makes an argument invalid or misleading, even when it sounds convincing.

from From Latin 'fallacia' (deception, trick), from 'fallax' (deceptive), rooted in the verb 'fallere' — to deceive or cause to stumble. The same trip-you-up verb gives us 'false,' 'fail,' and 'fault.' English borrowed it in the late Middle Ages, first meaning plain trickery, then narrowing to the more specific sense of a flawed argument that fools by seeming sound.
