From "Critical Analysis of 'Bling Bling'":
Although discussion of acts of violence is kept to a minimum in this particular song, several of the rappers make a point to indicate that resorting to physical brawls is not necessary for them to cause harm to others; their "bling" is mighty enough to cause blindness without the bearer of the "bling" so much as lifting a finger.
