Explanation: I already proposed an answer a few hours ago but it was a joke : I thought that this E-mail was a joke...
Now I realize that this is a serious query.
I am French and unfortunately we always use "tacos", even if we have a good level of education and even our charming girls do so,
"tu fais chier" is not a word to word translation but ans has nothing to do with "you suck" (tu suces- In French have a sexual conotation which means "you are doing a blow job" which we never use because in our culture, this is not an insult or a "bad world" but something normal in our sexual behaviour (never heard in English of the "French Way" ?)
Sorry for these very precise details (this is also culture and antropology and Dr Kinsey made a topic of it a few years ago).
So the usual equivalent in French would be "tu fais chier..." (something to do with excretion in the bathroom).
But please do not confuse with the expression (pronominal form) " tu me fais chier" wich is very different: in such a case, it means ( more or less : you bother me...),
"tu fais chier" is more like "you suck".
