This is my mothers word, it means to be nosey, pushy and a general pain in the ass. It sometimes means having an attitude the size of montana on your shoulders and projecting that all over the place. Generally this is not a nice thing but can be used in a nice context.
Derived from the word "nigger", but socially acceptable among the general population due to its infrequent use.
The use of this word in crowded areas usually results in a couple of turned heads, but no one is really sure if nigger was said. This adds the humour of the whole situation (unless the crowded area consists of strickly dark skinned people; then run for dear life).
