When the gags are not (too often) below the belt, they are predictable and simply not funny: during a ritual a character uses medical herbs and then asks "do you have basil? I brought a pizza" . Houlala the power of humor.
Lazy plot written (it made me think of the humorous short films of youtubers, that is to say ...): it progresses painstakingly, it skates (understand: there is no story, content or character). It does not play very well, apart from the 2 male actors but Will Forte overshadows what gives the film the comic maturity of a comedy intended for 8-10 year olds.
In short it is quite stupid, vulgar and uninteresting. I imagine that the American pie and the like look like this ...
