Got Up In My Grill

The other day, I heard someone say, "She really got up in my grill!"
I wondered what she meant.

My first thought: You got in my way and got up in my grill.

Or, same idea... more traumatic for both of us.

Then it occurred to me it could be a sports reference...

Boy #1 assured me that "grill" refers to teeth. 

Teeth?  

Like braces? 

Well... sort of. 

Grills are, in fact, fancy teeth. Jewelry. Bling.

Simply put: 

Got in my grill = Got in my face.

So, next time you see me at the dog park:

Don't get up in Carmella's grill!
