A sexual act involving at least 2 guys and 2 girls, which takes place on a staircase. A girl is on her knees at the bottom of the stairs, giving head to a guy who is lying on his back, further up the stairs. The guy is then eating out the next girl who is on her knees, further up the stairs and that girl is giving head to the next guy, who is lying on his back. This chain can be continued with more people as long as the guy-girl order is maintained. When viewed, the chain appears to look like the Great Wall of China. It is recommended that at least one person be Chinese.
Ex. 1: Hey Alix! Wanna have a Great Wall of China with me and 4 other random Chinese people?

Ex. 2: After last night's Great Wall of China, Melina had to scrub her stairs before anyone could get upstairs again.
