'Grunja' is a term now used by ignorant Chavs who are still taught that they should spell how they would say a word, and with their Janner accent it's no surprise that they could come up with a new word such as 'Grunja', 'Grunja' is actually just their dumb little way of stereotyping a Greebo (arch enemy of the Chav) as a Grunger.
Chav: "Oi! u fukin grunja, ya listening to that shitty Nirvana again?"
'Grunja': Speak in English please and maybe I'll be able to understand you.
Chav: "Don't start fukin dissin me! you startin on me like?"
'Grunja': *Blinks*
