Something of an oddity, & as far as I am aware, a rarity. Whilst most Chavs enjoy an unhealthy dose of jewelery/gold plated jewelery, those wearing Fake Bling are in possesion of a poor quality, cheap attempt at Bling. Fake Bling is often plastic, hollow & adorned with plastic diamonds & gold paint, one such example was a plastic padlock, that lacked a back, was painted with sparkly gold paint & worn in conjunction with a potentially real gold necklace by an extremely mo mo chav.

Briefly, "the realization that each random passerby is living a life as vivid and complex as your own." Originally from the Dictionary of Obscure Sorrows, which has a lot more beautiful neologism definitions like this you might enjoy.
