@wEATHERwAX, It's from a movie called Angus Thongs and Perfect Snogging. Some Nickelodeon movie from like 12 years ago. Can't remember much about it but at one point a guy refers to boobs as "nunga nungas" and explains that the name comes from the bouncing motion boobs do.
@megamanx181x, im gonma be that guy and mention how the males are called Bulls. Females are Cows.
Seems a lot of people don't realize this. Also males never have utters which Nickelodeon seemed to forget when they made Barnyard
