Herbie VerSmelt's definitions
The act of a man fucking a person doggy-style, while having a double ended dildo up his ass, and simultaneously fucking another person behind him with the opposite end of the dildo.
I was a runaway freight train on the San Francisco Railroad. My hips and ass hurt from all of the "chugging."
