Much like the dirty sanchez but a reversal. While giving head the woman sticks her finger in her bloody vagina and then smears it on the guys upper lip.
The were such a cute couple with their matching sanchezes... her with the dirty sanchez, him with the rusty sanchez.

To anal rape a female so that your penis aquires fecal matter on it, which you will then wipe on a rusty spoon, in which you will use to feed ketchup to the woman.
"Oh harry! That rusty sanchez was delicious!"
