A person who hangs around with cool people (one of which they are not) in order to become cooler. This method usually does not work, as the leech is usually a weirdo that will never be cool anyways. Bling leeching consists of creepy, stalker-ish following, trying to butt in to conversations, and dressing like the cool people.
"Dude, I wish that bling leech would stop following me around. He's making me look less cool."
