The Washington Post Mensa club invitational came up with some interesting new words which work well on these forums:
Karmageddon: It's like, when everybody is sending off all these really bad vibes, right? And then, like, the Earth explodes and it's like, a serious bummer.
Dopeler effect: The tendency of stupid ideas to seem smarter when they come at you rapidly.
Reintarnation : Belief that one will come back to life as a hillbilly.
