Originally from the TV series "Queer eye for the Straight Guy" meaning to spice up ones image/ make-up/ clothing and style. To make your appearance more attractive and eye-catching to others.
Don't you just love my new style, I decided to zhoosh it up and my self-confidence has also had a make-over!
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.
