An austrigger is an Australian nigger, someone white who acts black by wearing his pants around his knees, lots of gold-plate chains, over-sized watches and sunglasses, etc.
Walkabout guys are often austriggers, pretending to be black instead of Australian or Aborigine. Crying shame.
A person playing with the asshole in a sexual way (with toys etc.) and also gets turned on by it till the point where the asshole gets loose and flexible. Pretty handy for anal sex.

Girl: That's because I'm an assfrigger since I'm 13.
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.
