A term used to give an indirect importance to a noun. The word "it" obviously refers to what the person is referring to in general context as in:

"The Club? Down two streets, and take a left. On Sherbrooke street is where it's at."

But, it can be used when "it" hasn't been specified and the user merely intends to give it prime importance, such as:
"Simple Plan? No way, they suck big cock. The Rasmus is where it's at now."

Get the Where mug.
(idiom) an informal expression used to express that something has changed--usually for the worse--or that situation has developed into a particular state of affairs

Cultural context: "To where (it's)" is an effective and efficient communication tool. However, there is a socio-economic divide regarding it's usage. The expression is most often employed by yokels, commonfolk, and blue collar types. It is rarely used by their highly educated white collar counterparts because the phrase is foreign to some and consciously eschewed by others (e.g. the factions of yuppie douchebags who think their shit don't stink and pedantic stick-up-their-ass intellectuals who cherish proper grammar and strive to speak in paragraph form.)
"to where": The shift supervisor is never satisfied with our production numbers no matter how much we exceed target. It's gotten to where we're asking ourselves why we even try anymore...

"to where (it's)": Sure, the Mustang still runs like a raped ape, but sometimes the transmission sticks to where it's nearly impossible to short-shift on the drag strip.
