Three words: Tek No Babble.
When something went wrong in TOS engineering, Scotty OCCASIONALLY used one or two technical words to tell Kirk what was wrong. Occasionally. Meanwhile the drama continued, the mechanical failure serving to heighten the tension.
From TNG on, the story came to a rock-solid standstill while O'Brien or Geordi spouted 5 minutes of completely made-up words that made no difference to the plot at all, and we sat there waiting for them to finish talking so we could get on with the plot.
