Titantric
A type of sex that is so forcefully "hot 'n' heavy" that its vigorous oscillations can sink a huge ocean liner.
Supposedly just the act of Jack's and Rose's passionate kissing was all that it took to sink the infamous White Star liner (in the 1997 film, the ship's lookouts were distracted by watching the lovebirds making out, and thus they did not observe the iceberg in time to avoid a collision), but maybe the vessel's already-heat-weakened-by-the-coal-bunker-fire hull had been further fatigued by the lovers' previous Titantric lovemaking, and so perhaps the great ship would have gone down sooner or later in any case.
