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).
Pajama casual is a term used when working from home and preparing for a video conference. All business above the waist and your pajama pants down below.
We have a Zoom meeting in a few minutes and I’ll probably go pajama casual.
