"Do you get any sci-fi channels down there in Australialand, grug?"
A failed attempt in a particularly spectacular fashion, specifically pertaining to sports or video games.
"Did you see that Grug? It missed his bat completely"
"Oh dude, you Grugged that level. Perhaps Tetris is more your style."
Someone who urgently requires a haircut.
Grug was a childrens book character crated by Ted Prior in a series of books popular in Australia throughout the late 80s and early 90s.
Grug has thus become a popular nickname Australian people in particular, including but not limited to those with the name Greg.
True grugs, however, resemble the book character in that their face or body is covered completely by hair.
Thus one who is in dire need of a haircut is a
Grug. (or Cousin Itt.)
"Get a haircut, Ringo, you look like Grug."
