I've been enjoying immersing myself in cryptocurrency culture, which has as any culture, it's own lingo. "Hodl" means, roughly "Hold," as in, hold onto your bitcoins no matter if the market value is plunging or skyrocketing. Like the term "Pwn" (own) from gaming, it was spawned by a typo. Bitcoin has bucked like a bronco on its way up and down and up and down through the last few years. As I type this it's on a downward slide, but I'm sure a lot of people are still "Hodling."
