railing a line
To use only your nostril to snort meth or coke when nothing else suitable is available
That was some fire ice last night, sucks we couldn't find a straw. Railing a line is such a waste..
The Rail Line
The distinguishing line between a hot, sexy bitch and cute, adorable lady. With a sexy bitch, you just want to fucking rail the shit out of her, with no personal connection. You can do all kinds of weird kinky shit like cumming all over her titties when you pull your meat out of her steamy vagina. After your done you send that bitch home. However, with a cute lady you might want to take out to dinner and make her feel special. You take her home, maybe light some candles, and make sweet, passionate love to her. After your done you might even consider cuddling.
Dude, I didnt know how to handle this chick I was with last night. She was right on the Rail Line. I deemed her above the rail line, so we went back to my place and had rough anal sex and finished with a glorious donkey punch.
