1. When you and your roommate are both having sex in adjacent rooms and you both high five the dividing wall while having sex;

2. when any type of approving or applauding communication is made between two individuals having sex in adjacent rooms.

See Eiffel Tower, but with a wall separating the 4 individuals.
Tommy and I brought girls back to our rooms and pulled a Berlin Wall by high fiving the wall separating our two rooms while we were having sex.
