Funk in wine is new to me. So ... what's it all about?

So I'm a beer guy and though I love wine I typically don't drink it more than a couple times a year. Tonight I opened a Sicilian wine I bought within the past year (it's a 2014 if that helps) and the serious barnyard funk smell I most associate with real Belgian Sours punched me right in the face. Now I'm thinking, WTF is this? But it's not actually bad. Not all. So I keep drinking. And then I think, "I've got to figure this out". And with a simple web search I find out funk in wine is an actual thing. Seriously, somebody who know what's going on here, please enlighten me. Thanks in advance and cheers!
