Incidentally, "weirdness points" falls under this. Gratuitously using nonstandard terms (particularly geek pop culture related terms) makes Less Wrong look weird for little benefit. And LW already has a bad problem with not using standard terms for concepts.

I'm not sure that I have any weirdness points left /to/ lose. I'm fully signed up for cryo, which makes me weirder than 99.9999% of the population; throw in any other details about myself, such as atheism or schizoid personality, and I'm weirder still. ... That said, just last week I upgraded my wardrobe from nearly entirely t-shirts to enough button-up shirts to wear all the time, so I'm not necessarily /obviously/ weird. I don't plan on starting to swear any more than I do now, so adding an idiosyncratic swear-word to the ones I might draw from doesn't seem as if it would measurably increase how odd I seem to others.

Of course, YMMV, so an unusual curse-word that ties into your presumed anti-deathist leanings may or may not be worth the idiosyncrasy credit.
