Another name for snake bite piercings. The rings on either side of the bottom lip serve as rails to guide a dick right into your mouth.
Guy: "Hey guys, look at my snake bites!! I'm such a hard ass!!"
Friend: "You mean look at your dick rails. You're such a fag, I bet you can suck a mean dick with those things!!"
Everyone around the conversation: "Hahahahah!!!"
