Slang.
Gold, silver, diamond, platinum caps fitted over teeth. Usually worn by Black rappers, with the exception of the white/ wigger rapper Paul Wall. Conspicuous spending, meant to show that he/she is so wealthy, he/she can afford to put 'grillz' in their mouth.

Gold or platinum diamond encrusted junk moon crickets put on their teefus. A guarantee that a person has more money than brains.
Nelly putted some grillz on his teefus, then proceeded to ruin them with a bucket of extra crispy.

Those dumb ass things that some people think it's cool to wear on your teeth. it's oral jewelry,a waste of gold and diamonds,plus and it doesn't look good on ANYBODY. not even on nelly, who is the dead sexiest man in the world.
Grillz are stupid. Draw the line at the the bling bigger than your damn head. Leave your mouth alone,fool.
