Not sure on what a Boston steamroller is maybe you have it mixed up with a Cleveland steamroller, an act in which one partner defecates on the chest of the other partner and uses his or her buttocks to squish and spread around the feces over the chest of said partner.
In a Boston Pancake the partner who defecates must be male because after proceeding to defecate and spread the feces around he must turn around and point his penis towards the smeared area and proceed to masturbate until he ejaculates over the area covered in fecal matter.
