Bang Nail 

A condition where one has a hang nail or otherwise jagged portion of a fingernail and uses it to finger Bang a chick.

Glen fingered the fuck out of my Vag last night. It sucked though cause he had a serious case of Bang Nail :(

Rusty-nail bang 

When a man hasn't had sex for a long period of time, and is rusty from withdraw.

"I haven't done one in five months man."
"Man, that'll be one rusty-nail bang."
