I know "aiguillette" as a small needle, but would never had made the connection between that and a farking shoelace? :)
My bet is that without Google, there would be a lot more without a clue in that regard if they would only be honest enough to admit it.
Most of us, who have more important things to do, leave the discussion of shoelaces to little girls, shoe merchants, and ribbon clerks.
Live and learn ... and be honest enough to admit that you do.
