Rails 

Vaping several times in a row until the desired head high is reached.

“I went in the bathroom to fix my makeup but i can’t see shit in there because of the girls pulling rails on their vapes.”

Rails Before Pails 

The Hamsteak (homestuck) version of 'Bros before Hoes' using troll romance terms. Rails = Moirails, basically best friends. Trolls are said to use buckets to reproduce, hence the 'pails'.

Don't do this to me man! Rails before pails, we were supposed to hang out tonight!

Rails To Trails

An American faux exercise/railroad reclamation trend. Derelict train tracks are converted into foot and/or bicycling paths. The minute grades needed for the trains make the trails easily traversable, even by invalids.

I walked fifteen miles on the new Pine Creek Rails To Trails. I walked fifteen hundred feet, on a hiking trail and had to be Medevaced to State College Hospital.
