Is it true that If someone needs to sneeze and you say "pineapple" to them they won't need to anymore or is it just a mind trick?

So, a friend of mine told me that a few months ago and I didn't believe it at first but whenever she told someone pineapple (including me) I'd stop having the urge to sneeze. It's confusing.
