A celebratory phrase used following one, or a series of, positive, though generally insignificant event(s).

Its origin can be attributed to Milhouse, a character of television show The Simpsons, who coined the phrase in jubilation after realising the success of his flood pants to keep his cuffs bone dry.
"I left work 10 minutes early today, and I found $2 in the passenger seat of my car! Everything's coming up Milhouse!"
