An eifel tower involving three men and one woman. As such, one man takes the mouth, one the vagina and one the asshole. Other combinations are possible, but discouraged. The man taking the vagina must be laying on the ground, but still able to high five the other two people.
Dude, if you are going to break up with your girlfriend, at least ask him if she would be up for a treifel tower so Steve and I can also enjoy her last moments with you.
