A true red head's unshaved (preferrably nicely trimmed) vagina. The color of her pubic hair = red e.g. rusty, and box = vagina.
I love my smokin hot red headed girl friends "Rusty Box"! Did you see that ginger at the strip club? She had an awesome "Rusty Box"!

Last night, I spent hours licking her rusty box.

Going down on the ass and not caring about the fecal matter that may be present.
Man, I totally rusty boxed my dude friend last night. Tasted great.
