Ninnypuss 

A ninnypuss is a person that frequently annoys, angers, or upsets others.

My brother is a ninnypuss because he tries to act like he is the perfect child all the time, and he gets all the attention.

The part of the boob on a woman that spills over the top on a bra that is too tight.

Person 1 : "dude did you see those ninnypuffins sticking out all over?"

Person 2 : "yes they look liked a second set of boobs."
