As in "chav".
An ever-rapidly growing national underclass/sub species of human. Donning nothing else than designer sport wear.
Caring for nothing more (usually) than cars, brethren chavs and foul attitudes (and the odd pram, which will likely contain a chavling of which the jury is still out as to who is the father).
A "chavroglyphic" is similar to graffiti except it is not artistic & impressive.
It will probably look totally unintelligable to the regualar citizen.
A "Chavroglyic" will contain "glyphs" and other such chav associated slang. Only interpretted by their own crew, rivalling possies or freshly bred chavlings (young'uns).
Think egyptian "hieroglyphics", then you got it, hence "chavroglyphic(s)".
"Chow ma bitch, wid ma posse o dem crack'eds meet dem round dee carna, innit"
