Bus Transfer 

The sexual act of defecating halfway (turtle head) and inserting the now exposed feces into the anus of a loved one and/or neighbor. This "shit dildo" acts as a love connection between the two parties as they pleasure themselves, taking special care not to break it in the process.

"Did you get your tickets yet, Harriet Tubman?"
"Tickets? To what?"
"The Bus Transfer"
"The Bus Tr-?" *Splizzash*

Buffalo Bus Transfer 

To shit into somebody else's anus.

The girl that is known to have a gaping butthole would receive a buffalo bus transfer easily.
