"Fuck you" or, more literally, "Go fuck yourself"
This is the correct conjugation of the verb 'aller' because this is an imperative sentence. The imperative form of 'aller' in the second person is 'va.' I had to clarify this because there is another definition on this site, where the author vehemently states that it is 'Vas te faire foutre' and that is pretty obviously incorrect (for anybody who got past the first week of French 101).
Tu n'es qu'un con...va te faire foutre, putain de connard!
fous le camp, fiche-moi la paix, va te faire enculer, tu me fais chier, je t'emmerde
