To further escalate your friendship with a male counterpart and become related; in order to do this you must be in the same orifice as your friend at the exact same time . Also know as a train! Chu-Chu Motherfucker. I REPEAT THIS IS THE ONLY WAY TO BECOME KIN.
Bro are you wanna be my blood brother?!
Friend: I thought we already were!
Naw you're my best friend but to be my blood brother we gotta run a train together!
