A No-No refers to a perfect game thrown by a pitcher in baseball. NO hits, NO walks. It is commonly misused to refer to a no hitter in which walks were allowed.
Roy Halladay threw a No-No in the 2010 postseason. He is still a loser for being a Philly though.

In Puerto Rico, the word "ñoño" also means "coddled" or "spoiled rotten" along the same definition as "clingy" and "mama's boy" or "daddy's girl." It is very similar to the word "mimado," which means spoiled or pampered.
"Ese niño está muy ñoño. Le dan todo lo que pide sin ningún limites." (Translation) "That boy is spoiled rotten. They give him everything he asks for without any limits."
