Taking a piss in a urinal that has that pink cake deodorizer caged up in the bottom. You must exert maximum force so as to drill into the cake flaking off as much as possible during the piss session.

It is normal to have a goal in mind such as: I'm going to be first to bust through the cake, or I'm going to make pink lemonade.

Also known as "going to bust cake", "waging war on the cake", and "making the cake pay", and "ruining the birfday cake".
I'm looking forward to bustin' cake, my bladder is so full its making me scule.
