What is a "grillz" anyway?

I know you all think I'm an idiot for asking this (I don't listen to rap. Rap is stupid. End of story), but in the song "Grillz" by Nelly or someone like that, what exactly is a "grill"? I know it has something to do with teeth.

What is a "grillz" anyway?
your right, rap is stupid. A grill is metal things that they put on their teeth. Look at the Ying Yang(dumb and dumber) twins mouth.http://www.olsen-twins-news.com/multimed...

Reply:a grillz fits on the front of a car
Reply:they are stupid caps that cover your teeth (not permanantly) and can have diamonds or they can be gold (they can be other stuff too)
Reply:You're right. It's the gold and platinum teeth that are so popular. "up in you grill" used to mean "in your face". Grillz though, are not sexy.
Reply:When someone refers to your grill they are asking about your "teeth"...Someone with a nice grill has nice teeth...
Reply:they're lake the braces to straighen your teeth but they have dimonds ,gold or silver on them and make you teeth shine,you've watch the clip and you'll see the grillz when nelly sings
