Piss 'n vinegar

You gotta wonder where that saying came from. If it came from someone literally pissing vinegar, I imagine that would sting. You wouldn't want to be pissing too much vinegar for too long. But what is more likely, is our piss 'n vinegar shout-out went to someone building a brand. "Full of piss and vinegar" came to mean a youthfull go-getter who was on track to make something of themselves. There's not an official P&V rating system, but a lot of these folks show up on your "top 40 under 40" lists. They're not so much youthfull go-getters as they are establishment ass-kissers.
