the underground railroad

when a girl starts sucking on your balls, then licks your gooch, and finishes it off with a rimjob. It's a funny experience that feels great, but is secretive just like the real underground railroad from back in the day.

So last night this slam piece was sucking my dick when all of the sudden she gave me the underground railroad

the underground railroad

The toilet and/or the entire human fecal system.

Called the underground railroad because "black shit escapes."

Goddamnit, I better go visit the underground railroad.

underground railroad

A clever escape route, or the act of leaving a crowded place or a sticky situation, without anyone noticing until long after your gone.

"Hey, anyone seen Tom?"
"yea..like a half hour ago by the keg"

"Damn, He must have hit the underground railroad"

Underground Railroad

When a train captain drives a train into a woman's vagina.

Man 1: Did you fuck her?

Man 2: Yea, but she was loose enough to give an underground railroad.
