bouncy ball rubiks cube

A sex position in which both partners pretend to be children and the male partner takes a cubic shape while the female partner "bounces" on the "Rubiks Cube" in a ball-like shape, attempting to "solve" the cube.

I heard Dustin and Megan did the bouncy ball Rubiks cube at last night's party!

4x4 Rubik's cube

A Rubik's cube that has more turns than a 3x3 e.g. Rw or Bw2.

I have a Qiyi 4x4 Rubik's cube! I love it!
