when one man(or hairy woman) pulls up their shirt and sticks their hary armpit in the face of a friend(or mortal enemy) and holds it there until it seems as though they will pass out.
"hey Bill, do you want a yeti?"
"what's that?"
"this" (pulls shirt up and gives yeti)
"ooh"
It's what I call my own pet (unfit mother) Abominable Snowmum. I get one all to myself, aren't I lucky? It was worth watching Suburban Mayhem just to see my own 'best in show' pet Yeti's biography on screen...
Anything you can insert the word mother into. "Hang on, don't we have to go to Yeti's for Christmas?" ... "Why, I haven't bothered for the last 5"...
