|1.||harder than Chinese calculus|
A phrase used to describe an extremely difficult task or how hard an object is. The inference is that calculus is difficult by itself and in Chinese, a seemly nonsense language compared to English, it is extremely hard. Etymology: Midwest slang.
That girl is so hot, she makes my dick harder than Chinese calculus.
My grandpa said "trying to program my VCR is harder than Chinese calculus."
