When the toilet is filled with brown water, either because the toilet was clogged with shit, or the toilet just had shit sitting in it for too long. As a result, the toilet looks like a big cup of hot cocoa (but sure as hell doesn't taste or smell like it).
Damn! Someone call the janitor! The boy's bathroom's gotta cocoa toilet goin on in it!
