Rubik's Cube 

To pour six cans of paint on your head (each of them representing colors on an actual Rubik's Cube), which you penetrate your girlfriend's ass and vagina with (either order is fine) while ramming it as far up as possible and violently nodding during both processes for maximum pleasure. Consent is not required.

That kid's vagina smelled great during that Rubik's Cube. Her ass was not so beautiful.
