What is this expression? Pronounced, approximately as... "Kay Wy".
I hang out with a bunch of people and this term/exclamation comes up quite constantly. Seems to be an expression of pleasure; "how nice"; "cool" or something of that sort. My dictionaries and online searches have yielded no results as of yet.
Anyone familiar with it and it's 'proper' usage?
If so... "Qué guay!" ... & let me know too.
