Are you starting a (venture-scale) company? Learning this language is critical.
Are you working for a startup? Becoming more familiar with this language is helpful - you can figure out whether the founders/executives know what they're doing or not.
Are you working for a large company? Learning this language will not provide much benefit for you IMO.
If the answer to either of the first two questions is yes, where would I go to learn the jargon? (I do know about google, I'm just hoping there's a good resource that has everything so I don't need to search individual terms).
Venture Deals by Jason Mendelson and Brad Feld is a good overview. If you want to get more technical, the NVCA publishes a list of their own "standard" documents, which go into depth on some of the standard and non-standard provisions and what they mean, but it's not quite as user friendly.
