I thought I'd help cray clear up the confusion once and for all, so I did some in depth google research:
pip: 1. a tool for installing and managing Python packages. 2. the smallest price change that a given exchange rate can make. 3. personal identity portal.
nib: 1. the part of a quill, dip pen or fountain pen which comes into contact with the writing surface in order to deposit ink. 2. a small pointed or projecting part.
pid: 1. pelvic inflammatory disease. 2. a platforming adventure game by Might & Delight
That should clear things up..
