1. A denial or shutdown
[ Origin: While I'm sure the saying is common in sports vernacular, it was brought to my lexicon by Erik]
1. "Manu Ginobili went up for the shot, but Amare gave him the no-no and knocked it 6 rows in to the crowd."
2. "I finally beat Bowser on world 4-4, but instead of the princess, all I got was the no-no"
Not to be confused with the no-no naughty-spot.
