Pajama 

When you sneak up on a sleeping person while they are sleeping on their stomach and have anal sex with them, without waking them up.
Comes from old times, when the butt flap was still popular.
Note! There must be no consent for this to work properly.

John: Dude, you and your woman have a good time last night?
Jack: Yeah, I pajama'd her and she didn't even make a noise!

Pajama day

A day, usually on a weekend or during a day off, when you have nothing to do and sit around lazily in your pajamas, not leaving the house. Often involves eating cereal for every meal and excessive television/video games.

Speaker 1: "Hey, want to go see a movie?"
Speaker 2: "No way man, I'm having a pajama day. Let's just sit around and watch Seinfeld reruns."

pajama walkers 

People who wear pajamas outside of the house.

Holy shit! Have you been to Walmart lately? With all those pajama walkers it looks like a white trash The Walking Dead.

Pajama Jammy Blam

“Pajama Jammy Blam” - the enviro safe practice of ejaculating into your sleeping attire from the night before. The idea being to eliminate the need for a towel, sock, or Kleenex. It’s an environmentally responsible way to help your household become more sustainable by reducing laundry loads.......

I’m doing my part to help cut down on unnecessary laundry by utilizing the Pajama Jammy Blam.

The wife rolled over with a headache first thing in the morning so I had to resort to a pajama jammy blam to get my day started.
