The German Totem pole is a sexual act which requires a minimum of three men, sitting on each other's lap, resembling a totem pole. They each insert their phallic member (which at this point should be rock hard) into the man above. A woman could be positioned at the top of the totem pole for decorative purposes only.
Oh man you rocked the top of the German Totem pole last night! Your arse was packed!
Did you hear about Steve? He was at the bottom of a 10 man German Totem Pole last night, he came for days
