lalochezia
The use of vulgar or foul language to relieve stress or pain.
rare, uncountable
Morton's heavyhanded humour when he denies imagined accusations of coprophemia, aischrolatreia and lalochezia by saying that "you - dear reader - can decide for yourself after perusing the remaining two hundred pages" is made heavier still by the fact that nobody at Atlantic noticed that this estimate is 100 pages out.
Where it comes from
From Ancient Greek λάλος (lálos), λαλέω (laléō), λαλιά (laliá) + χέζω (khézō), equivalent to lalo- + -chezia.
