Glorious, elaborate, profane insults of the world

An open Reddit thread entitled "What are your favorite culturally untranslateable phrases?" rapidly degenerated into a collection of rollicking, profane, grotesque insults, each more alarming and delightful than the last. Read the whole thing, of course, but here are some of the less profane examples:

* The Dutch phrase for giving too much attention to insignificant details is "ant fucking".

* Afrikaans: "Jou mammie naai vir bakstene om jou sissie se hoerhuis te bou Vieslik!" your mother engages in prostitution in order to raise funds for the building materials necessary to construct a brothel from which your sister will operate.

* German: "backpfeifengesicht" - a face in need of slapping

* Finnish: "Kyrpä otsassa" - a vulgar way to say you're incredibly annoyed. It means that you have a dick in your forehead (should be visualized as hanging forward, rather than actually in your forehead, for some reason).

* Finnish: "pilkunnussija" - a comma fucker; someone who corrects little or meaningless things.

* Spanish: "Está tratando de cagar mas alto de lo que le da el culo" - He's trying to shit higher than his ass can reach.
