Unexpected cult comedy

An unexpected cult comedy that is way too excessive up till a point that the whole theme is actually trying to be as excessive as possible, and somehow it turns out to be fun enough. It was metaphorically accurate about lovers' quarrel although most of the situations are obviously exaggerated, but sometimes absurdity indeed does not need much logical sense. Well, the closing part is still oddly satisfying, which is super weird because the plot is something that should be taken with a grain of salt.
