Neff-neff is Belly-Button fluff. Save enough and you can stuff a pillowcase with it!

I just bought a huge neff-neff pillow. Must have taken 10 years to collect all that shit!

random neff 

A random person who tags along with groups of people who he never usually interacts with. Occasionally he will speak up, and everyone in the group will look at him funny because no one is friends with him.

This term was created students 10 years ago to insult random people whose intrusive behavior resembled a science teacher named Mrs. Neff

There was this random neff Mendy's party the other night who started talking about how beer is bad.

When your last name is Neff and someone decides that means your first name is Jeff. Usually happens when someone is reading your name off of a list.

Teacher: Jeff Neff.
Person: Here, but my name isn't Jeff
Teacher: oh sorry.
