Knuckling 

Knuckling is the act of 2 bros fist bumping eachother. As the two bros fist bump eachother, a third bro proceeds to slide his dick between the other bros touching knuckles. He then proceeds to fuck their knuckles.

Rusty Knuckles 

Similar in VERY FEW regards to "Bloody Knuckles" that we played as kids....

"Rusty Knuckles" is simply (depending on your particular 'acceptance' of said limb) the act of anal fisting.

does this really need an example?

I guess....see goatse.cx for historic reference?

"Oh man, Justin and Andrew were having playtime.....Justin was stretching for his receiving of Andrews clenched fist. I bet he has Rusty Knuckles now!"
