nannipacker 

One who takes a long time to pack a pipe or to pass a pipe.

Joe was waiting patiently, but Pete kept on talking while holding the pipe.
"Quit being such a nannipacker, Pete, and pass that pipe," said Joe.

nanpacker 

Just an insult... doesn't have much meaning behind it, just means that they're an old fool.

Go away you fucking nanpacker
