When you want a woman to show you her "titties" via pulling one from her shirt in a quick fashion.
This can also mean sending a picture of her "titties" in anyway too.
"Hey babe can you pop a tit?"
"Yea sure, let me take off my shirt and bra."
"awooga! those are nice titties babe"
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.
