Climbers have a very particular vocabulary. If any outsider were to eavesdrop on a conversation between climbers for even five minutes, they would leave very confused and probably disgusted. Our slang terms get slangier, and shortened, and misspelled until we're left with a language so exclusive, that I'm still learning new words all the time — and I have been in the climbing game for about 13 years now. I compiled a list of 20 of the most common climbing terms that y'all might be interested in hearing the origins of. Let me know if I missed any! GriGri: Believe it or not, the term "GriGri" is derived from Voodoo. Yep, spell castin', doll stabbin' Voodoo. In Voodoo, a "gris gris" is a good luck talisman — thanks to its auto-locking feature, I'd say the GriGri is a pretty good luck charm against your partner's crappy belaying. So be sure to make an animal sacrifice to the Petzl gods, in appreciation for them creating you such a glorious device.
