In one of the VW commercials that I like, right after demolishing some dude's pimped up ride, VeeDub says "OH SNAP!"
Disclaimer: I have no idea what "OH SNAP!" means, so if it means something really bad, please forgive me. I don't think it does, though and I felt like what you posted deserved an "OH SNAP!
Actually, I know a lot of people that use that.
It's the equivalent of "oh $#!t"
Kinda like darn and gosh and shoot...so to speak.
